Fractals are incredibly complex mathematical equations,
which create seemingly endless, breathtaking patterns. Below is an example of
an equation, and some pictures of naturally occurring fractals, as well as
computer generated fractals. As you can see, they are awe-inspiring, even
intimidating concepts.

The way the human body is made and functions, is even more complex. It contains patterns as well, but more specifically, it contains small
details which build into the incredible functioning unit of … you!
Learning about the building blocks of the human body reminds
me of those pictures that you have to stare at extremely close up and then back
up, in order to see the big picture. I’ve posted a couple of them below, in
case you weren’t familiar with what I’m talking about. In these pictures below,
you cannot fully understand, or ‘see’ the big picture until you first start
looking up close.
Shark? Dolphin? Mermaid?
Yum.
Lets look at this like one of those Russian Nesting dolls.
You open each doll and get to the smaller one inside.
Cell-tissue-organ-system-YOU!
Expanding that idea to the human body, when you look up
close you find that the body’s smallest living unit is this tiny thing called a
cell. Of course there are all different kinds of cells, over 200 different
types make up the human body. The cells have even smaller things inside of
them, called organelles, and these tiny things are the “organs” of the cells,
working hard to make the cell work.
When you get enough cells together, with similar goals and
missions- think of it like the cells picking teams.
(Who wouldn’t pick Duke?)
(Who wouldn’t pick Duke?)
Look! Duke "tissue!"
Once the cells decide what they are going to stick together and accomplish, we
get tissues. There are four major types of tissue in the body: Connective
tissue, epithelial tissue, muscle tissue, and neural tissue.
Connective tissues do just what you might think they do-
connect the different tissues together! But, did you know- blood and lymph are
also types of connective tissues.
Epithelial tissue is most likely what you think of when you
think of tissue. It is what makes up your skin, and has some component in most
of your other ‘soft’ organs like the liver, bladder, kidneys, heart,
gastrointestinal tract, etc.
Microscopic look at epithelial tissue of kidney
Muscle tissue- well that’s fairly self-explanatory isn’t it?
There are of course different types of muscle tissue. Ones that you control:
the ones that walked you to class on time, and that you work out in the weight
room, are called skeletal muscle. The ones that do things without you thinking
about it are called smooth muscle tissues- like the ones in your arteries.
Finally, there is cardiac muscle tissue, found in…where else, but your heart!
Finally there is neural tissue, found only in your brain,
spinal cord, and peripheral nervous system. This is the tissue that sends and
receives messages from the brain and tells your body what to do, both with your
knowledge and without.
Just like the cells pick teams, the tissues also have to
pick, for the sake of a visual, a team to play for or in other words, a
function to perform. No one gets to be lazy in the human body. When tissues
pick their “sport” or function, they group together and form organs. Now we are
getting to the things you are most familiar with.
Each person in this picture picked a sport or "function", like tissues to organs
Organs group together and form body systems, 11 in total,
which in the next blog, we will look at in depth.
As you can see, the human body is endlessly difficult to understand, complex, layered, and more incredibly both the same and different
from person to person than the fractals in snowflakes.

Discussion Questions
1. Explain in your own words the relationship in the human body between cells, tissues, organs and systems.
2. Click on the hyperlink on the word "cell". Go to the website and learn simple things about the different organelles. Which organelle stores DNA? Which organelle is the energy source for the cell? How are the organelles similar to your body's large organs?
3. Name some other types of connective tissue. Upload a photo in your comment of a type of epithelial tissue. Where else is smooth muscle tissue found aside from arteries?
4. Click on the link "endlessly difficult to understand" right above the snowflakes. This will take you to a website. Click on sensation and watch one of the three videos. Describe in your own words what you learned about the nervous system/ neural tissue.
5. On the same website, click on Strength. Watch one of the three videos. In your own words, describe what you learned about muscle tissue. Then, look at the diagram to the left and enter your weight. How much force is put on your body when running? Climbing? Jumping?
1. Cells, tissues, organs, and systems are all related to each other because cells are what make up tissues; tissues are what make up organs; and organs are what make up systems. All together, they make up the human body.
ReplyDelete2. The Nucleus stores DNA within the cell. Mitochondria is the organelle within the cell responsible for storing the cell’s energy and enabling it to move. The cell’s organelle’s are similar to the human body’s organs because they all have a separate job or function that they do best and when they are put together they create something larger. Everything within the cell works together to make a cell and to keep it functioning properly, just like all the body’s large organs work together to keep the body functioning properly, too.
3. Some other types of connective tissues are tendons, the connective fibers surrounding the muscles, and the ligaments and capsules surrounding the body’s joints. Besides being found in arteries, smooth muscle tissue is also found in the body’s blood vessels and veins.
4. I watched the second video about the nervous system and I learned that our body has tons of tiny nerve sensors right below the skin. They sense when our body temperature is outside of the normal temperature zone and fire signals to the brain. The brain then tells the body to sweat, which is the body’s most effective cooling system that helps to keep us alive. Once the body runs out of water, though, the blood has to thicken and causes the heart to draw more water to the lungs and heart to keep the body cool.
5. I watched the second video on “Strength” and learned that our bone mass is made up of tiny pores that are alive. They are spongy and soft on the inside, not just a hard mass. They are also harder than concrete. I also learned that bones are flexible. I never knew that before. There is 330 pounds of force on my body when climbing, 660 pounds when running, and 990 pounds when jumping.
**I'm not sure how to upload a photo here. I tried copying and pasting, but it would not let me paste here.
1. Organs and cells are related because there is organs in the cells called “organelles” and they are what make the cells work. Once the cells connect to each other they form tissues. Organs also connect to each other to form body systems.
ReplyDelete2. The organelle that stores DNA is the Nucleus. The organelle that is the energy source of the cell is the Mitochondria. Organelles are similar to our body’s large organs because they both have an important part in the body to make in work. The organelles are small organs so they are very similar to large organs.
3. Some other types of connective tissues are Epithelial tissues , muscle tissue, and neural tissue. Blood and lymph are other types of connective tissue in your body. Smooth muscle tissue is found in the aorta along with the arteries.
4. What I learned in the third video is that we need pain because it helps us to know when something is wrong with us. The pains goes up your spinal cord and into your brain which then allows us to feel the pain from the injured area that needs to be fixed. If we didn’t have this process in our body’s we wouldn’t be able to know when our body’s were hurt and needed to be fixed because we wouldn’t feel anything wrong with our body’s.
5. Muscle works by contracting and extracting which allows us to move. In extreme danger we are able to do things that would normally be impossible but because of the adrenaline in our body’s we are able to move them even though we couldn’t do anything near this amazing without the adrenaline. When I am running there is 480 lbs. of force on my muscles, when I am running there is 960 lbs. of force on my muscles, and when I am jumping there is 1440 lbs. of force on my muscles.

1. I think the human body is all connected and it works together. Every cell has its own specific job and it
does what it needs to do. Every system in the body works with the cells, tissues, and organs as well. If our
body didnt work together we wouldnt function the way we would and probably wouldnt be as healthy as we
are.
2.The Organelle that stores DNA is the Nucleus. The Organelle that gives a cell its energy is the
Mitochondrion. These Organelles are similar to our organs because they do the same things for plants and
animals as our organs do for us.
3. Some examples of connective tissue are the inner layers of skin, tendons, ligaments, cartilage, bone and
fat tissue.
Smooth tisues are not found just in the arteries but they are also found in the Iris of the eye and also the
urinary bladder as well. Also it is found in the male and female reproductive tracts and is also found in the
uterus.
4. I did video number two and what i learned is that when our bodies get to hot our body sends a signal to the
brain syaing its to hot and then the brain sends a signal to the nervous system to cool down our bodies so
that way we can survive the hottest of areas and the coldest of ones too. When we are to hot one way of
cooling down is by sweating a lot. Sometimes the heat is so overwhelming that your mind starts to
hallucinate.
5. What i have learned about Muscle tissue is that your muscle tissue is very strong and when they contract
they can lift up to 1 ton and they have the ability to really save your life. When i am running i have a force of
750 pounds. When i am Climbing i have a force of 375 pounds. When i am Jumping I ahve a force of 1125
pounds when i jump. And this was my Human Machine paper.
1. The relationship in the human body between cells, tissues, organs and other systems is that they all have to work together to make the body function. None of them can be lazy. All of them have to pick something to do in the human body. Once they’ve found something to do they start gathering organs and getting it done.
ReplyDelete2. The organelle that stores DNA is the Nucleus. The energy source for the cell is the mitochondrion. How the organelles are similar to the body’s large organs is they both have to work so the cell or body can function. For example if all the organelles stopped working in a cell there wouldn’t be a cell. The same thing would happen to the human body if all the organs just stopped working.
3. Other types of connective tissue would be cartilage, muscle, and epithelial tissue. Smooth muscle tissue is found in the walls of the digestive tract, bladder, and blood vessels.
4. What I learned about the video of the father and daughter getting stuck in the dessert was that the nervous system is the only thing keeping you from frying out in a dessert like a piece of meat. The nerves warn your brain of the loss of water and high temperature. Your brain then tells the organs in your body to move most of the water in the body to the heart, lungs, and kidneys where it’s most needed. But if we didn’t have a nervous system we would just fry in the sun like a piece of meat.
5. What I learned from the first video about the muscle tissue is that it has cords that contract which makes the muscle move. We usually use only 1/3 of our muscle at a time. But at extreme measures we can use our whole muscle to get us out of a dire situation. For example in the movie where he lifted the one ton rock off himself. The force put on my body when running would be 720lbs. When I’m climbing the force is 360lbs and when I’m jumping the force is 1080lbs.
1. I would explain the relationship between cells, tissues, organs, and the human body as a pyramid. The very bottom square is your cells. The bottom square is the biggest because there are more cells in your body than any of these other things. Cells are the basic building block of the human body; in order to have any of those other things you need cells just like the base of a pyramid. The next biggest block would represent tissues. Cells make up tissues, in order to have tissues you need to have cells. The next block in our human pyramid is organs. There are even less organs in your body than cells or tissues. It is impossible to have an organ without having tissues or cells because tissues and cells are what make up organs. Just like in our pyramid without the bottom blocks the top blocks would have no place to be. The final block is the human body all together. It is the smallest block and is on the top to complete the pyramid. The cells, tissues, and organs build up to create the human body.
ReplyDelete2. The organelle that stores DNA is the nucleus. It is the center of the cell kind of like the yoke of an egg. The organelle that is the energy source of the cell is the mitochondria. I have heard it described as the battery or workhorse of the cell. The organelles are similar to the organs in your body in the way that the organelles make up the cell just like the organs make up the body. All are important (to some degree) within the body /cell.
3. Some other types of connective tissues are cartilage, bone, adipose, and hematopoietic tissue. Smooth muscle tissues can also be found in the lining of your stomach, your intestines and your bladder.
4. I watched video number 2 and in this video I learned that when you skin gets too hot (above 98 degrees) nerves in your skin send messages to your brain telling it that you are too hot. Your brain triggers your cooling system, sweating. Water is extracted from your blood by millions of sweat glands and excreted onto your body where it evaporates, cooling your body.
5. I watched video number 1 and i learned that your muscles work by contracting at a microscopic level. All the muscles fibers are bound together like a bundle of wires to make your muscle. I also learned that you are born with all the muscles you will ever get, although they may get bigger or smaller.
Force put on my body while-
Climbing- 330 pounds
Running- 660 pounds
Jumping- 990 pounds
1. Inside of the human body, there are lots and lots of cells. Cells are made up of individual little components that make the cells work, much similar to how tissues and organs are made up of each other. Cells make up tissues, and tissues make up the organs of the body.
ReplyDelete2. The organelle called the Nucleus is the organelle that stores the DNA inside of a cell. Mitochondrion is the organelle inside of cells that provides the cell with movement. Organelles are similar to our bodies organs because parts make up each part of the cell and parts in the body make up organs.
3. Other types of connective tissue are ordinary/special, loose/dense, regular/irregular, fibrous, elastic, adipose, lymphoid, areolar, blood, bone, and cartilage. Smooth muscle is also found in the stomach, intestines, and the bladder.
4. I learned some interesting things about the nervous system. Our body has detectors all over to detect if we are too hot and tell the brain if we need to cool down. If we need to cool down, we usually sweat because sweating is the best way to cool off. When we are dehydrated we will hallucinate.
5. Muscle tissue is a very interesting part of the body. It is what is used to help us move around. When we exercise, after a certain point of time we experience exhaustion. If we keep going despite the exhaustion, our body will “cannibalize” itself. What that means is that your body starts “eating” the fat cells of our bodies. Our bodies never actually lose or gain fat cells, but they grow or shrink. Which in this case, the fat cells are shrinking. I weigh about 176 pounds. This means that when I am climbing I use 528 pounds of force, when I am run I use 1056 pounds of force, and when I jump I use 1584 pounds of force!
1. The relationship between our cells, tissues, organs, and systems is that cells make up the tissues; tissues are the components in organs; if your system does not have organs then it cannot function. Without any of these your body would not work.
ReplyDelete2. The organelle that stores DNA is called the nucleus. The organelle that is the energy source is called the mitochondrion. These are similar to my body’s large organs because my cells have close to the same model. My cells make up the tissues that make up the organs that are in my body.
3. Some different kinds of connective tissues are your blood and lymph nodes. Smooth muscle is found in the organs. Specifically it is found in your stomach.
4. One thing I learned from watching the video is how incredibly fast our nerves can work. I also learned that our pain nerves move slower that any other nerves. The signals sent from the area in pain jumps from one nerve ending to another. If you are a lot of pain then your body secretes a chemical that stops the pain. It does not always last a long time. The amount of time it lasts depends on the amount of pain you are in. The chemical that your body secretes is called endorphins. You do not always feel pain the second it hits you.
5. When we use our muscles we end up only using about one third of our available muscles. Our muscle tissue is very intricate. Our muscles can lift things in tough situations. We have had and will always have the same number of muscle fibers. The amount of force I put on my body when running is about 756lbs. the amount force exerted on my body when climbing is 378lbs. the amount of force exerted on my body when jumping is 1134lbs.
1. The cells are what make up tissue. When they stick together, then tissue is formed. Then the organs are made up of 2 or more tissues. Then the systems are made up of all the organs in the human body.
ReplyDelete2. The Nucleus is the organelle that store DNA. The Mitochondrion is the Organelle that provides energy. They are similar because they have all the basic organs like we do to servive. Like digestive and hormone organs.
3. Other types of connective tissue is: Cartilage, bone, and adipose tissue. Smooth Muscle tissues are also found in the urinary bladder, in the iris of the eye, and the arrector pili of the skin.
4. I learned that the nervous system translates what is going on to the brain and that the brain relays that message on and sends out signals to move your body parts. I also learned that there are about 45 miles of nerves. And there is no other computer that is more complex than our nervous system.
5. I found out that muscle tissue works by contracting. We are born with all the muscle fibers we will have. I also learned that we aonly use 1/3 of the muscles in our body at one time. When climbing I have 447 lbs of force, when running I have 894 lbs of force, and with jumping I have 1341 lbs of force.
The Human Machine
ReplyDelete1. The relationship between cells, tissues, organs, and systems is amazing. The human body alone is amazing, but what it is constructed of really creates the “wow factor” in how truly magnificent it is! From the outside, it looks like one, whole being… but in actuality, billions of cells, organs, tissues, and other things are working inside it to make it look this way! All life begins within, or at, the cell. There could be absolutely no life without these incredible structures. Then, these structures, come together to create tissues. Tissues are a group of related organs working together to perform a certain task in the body. Now that these tissues have banded together to be components in our important organs, the next thing up is organs! Organs do specific things they were made to do, like the kidneys secrete waste from the body. Finally, organs come together to make up all the different systems in our body to function and work together properly. Do you see, now, how all these little things net into the whole body?
2. There are two different types of cells: prokaryotic and eukaryotic. Both carry DNA. However, only the eukaryotic cells have mitochondria, which give store and release energy! Organelles are similar to our body’s large organs by that they both work fluently with the whole being it’s specialized to operate.
3. Some other connective tissues are the following: fat, cartilage and bone. On the other hand, smooth muscle tissue covers the organs in your body that you cannot control. The small intestines, large intestine, kidneys, liver and so on, are all examples of where smooth muscle tissue is located.
4. The sensation video I chose to describe was the one about pain. It talked about how pain is probably the worst part about the nervous system, but perhaps the most crucial. Without pain, we wouldn’t be able to sense if something in our body wasn’t functioning properly or if our body was being externally harmed. I learned that our bodies have their own painkiller. When the brain wants to minimize pain, it sends signals, which release a type of chemical that suppresses the pain. These “painkillers” have two hundred times the power of any kind of medicine, like morphine.
5. For the second sensation, strength, I chose the video about a man being thrown around by a tornado, smacked down to the ground, and not breaking a single bone! The strength of the human bone and its flexibility is astonishing! The man’s bones completely protected his internal organs from receiving any damage, which proves that bone is stronger than concrete rock! The amazing, living cells found in bone make it light and flexible, as well as enable it to withstand thousands of pounds worth of compression. I learned that when our muscles are relaxed, it is easier for the bones to obtain shock. When we run, jump, or climb, our bones absorb pressure worth hundreds of pounds, depending on your weight. For example, for my weight, when I climb, my body takes on 372 pounds of force; when I run, it takes of 744 pounds; when I jump, it takes on 1,116 pounds! Wow! Our body is genuinely spectacular.

1. There is nothing more important that the strength of the relationship between cells, tissues, and organ systems. If there were not any cells there would not be any people, matter, or even a planet Earth for us to live on. If there weren’t any cells there would not be tissues or organ systems for me to right about. I have recently found out that we have found over two hundred different kinds of cells. Cells are kind of the building blocks of the human body. As you open these microscopic building blocks you find even smaller pieces to this complicated puzzle. When the cells bind with each other they create tissues. Tissues are the very material that organs are made of.
2. Perhaps the most important part of the cell is the Nucleus. The Nucleus is the biggest part of the cell that holds your bodies DNA. Your bodies DNA is what makes you, you. Your DNA holds your personality and characteristics. The part of the cell that controls your body’s metabolism and it is also like your bodies energy source. You can see many similarities between the body and the cells in your body, the body is made of various organs, and cells are made of tiny, microscopic parts to perform various tasks.
3. One type of connective tissue is the epithelial tissue. Its use is making the bodies skin. There is also the muscle tissue that makes up your muscles. Muscles tighten and expend to help the body move. The final kind of tissue is the neural tissue. The neural tissue is found in your spine, brain, and nervous system, and the task it must perform is to send the brain messages.
4. When I watched the video of the human eye I learned that it takes thirty minutes for our eyes to use its natural night vision. When we can see clearly in the dark, our eyes can detect light and that is what helps us see. When the light is detected, messages are sent to the brain that tell us what, and where things are.
5. After watching the next video I found out that muscles contract and literately pull on the bone as if it were a lever. Also tiny muscle fibers slide past each other causing them to contract. When I typed my weight into the computer I was told that I withstand 375,750, and 1125 pounds of pressure when I climb, run, and jump.
1. In the body, cells join together to become tissues. The tissues come together to form organs, and the organs group together to form systems in the body. There are multiple kinds of tissues and many different organs that make up the body. Ones that perform similar functions are the ones that are grouped together into organs and systems.
ReplyDelete2. The organelle called the nucleus stores the DNA in the cell. The mitochondria powers the cell and most of its functions. The organelles are similar to our body’s organs. The organelles are like the organs of a cell. They allow the cell to function properly, just like the organs in our body keep us alive. Their names also suggest that they are similar because the word organ is actually inside the word organelle.
3. A type of connective tissue that was not mentioned in the blog is bone. Bones hold all of the other tissues up and support them. Without bones we would be a useless pile of flesh. Another kind of connective tissue is cartilage. It is found in multiple areas of the body, including around your body’s bones. The cartilage reduces friction on the bones. Smooth muscle tissue can also be found in the esophagus and the intestines. These smooth uncontrollable muscles push food throughout the digestive system.
4. I learned by watching the third video, that pain is a system of defense in the human body. It tells the brain the body is being damaged. I also learned that pain is processed all over the brain. The nerves scattered around the body gather information about the body’s condition. If you have an injury, these nerves send signals to the brain warning it of the damage. Pain is the brain’s reaction, telling us that we need to stop hurting ourselves, and telling us to get help.
5. While watching the third strength video, I learned that the body uses carbohydrates for energy until they run out, then the body starts utilizing the fat cells in the body. This energy allows athletes’ muscles to continue functioning. Even though the brain tells you to stop, and you keep going, this is when the fat cells in your body start shrinking. When I put my weight in the diagram, it said that 480 pounds of force is put on my body when climbing, 960 pounds when running, and 1440 pounds when jumping.
1) To me the relationship between cells, tissues, organs, and systems is the cells make up the tissues, then the tissues make up the organs, and finally the organs make up working systems.
ReplyDelete2) The organelle that stores DNA is the Nucleus cell. The organelle cell that's the energy source of the cell is the Mitochondrion cell. The organelle's are similar to our body's large organ by how both the organelle and our human organ are made to protect whats inside your body.
3) The 3 types of connective tissues are loose, dense, elastic, and so on. Another place for the smooth tissues are found is the veins.
4) I watched the 3rd video and what I learned that the nervous system fires pain. The pain is here to protect us to alert the brain and gives the time for the brain to access it,that's why its takes a while. Once you get hurt, the pain starts but doesn't go to the brain first, it hits the spinal cord. The signal gets passed from nerve to nerve and then send it to the brain. When the brain wants to stop the pain, it flows chemicals through the spinal cord and it makes you feel no pain. The chemicals keep your mind off of the pain until you relax, then it kicks in again.
5) I watched the 1st video and what I learned that if your stunned, your muscles are still active, alive, and awake. The muscle tissue works by contracting, which is basicly pulling the bone using it like a lever. There are 1000's of individual fibers put together like wires of cable. Even though they get bigger or smaller, we will get all the muscle fibers we got. In each fiber, there are smaller filaments to activate each muscle. Once the muscle fiber gets shorter, its in charge of all muscle movement. We can unleash all the power in our muscles and lift things heaver than us, which is impossible to do. I entered my weight and all the force that I put into my body when I climb is 549. When I jump its 1647. Finally when I run its 1098.

1) The best example of showing the relationship of systems, organs, tissues and cells is probably the ladder example we went over in class. First we have systems which are made up of selected organs that help the system function correctly. Next we have tissues which are cells that have become a group to take on a special task. Last we have cells which contain various different parts such as a nucleus, nucleolus, the endoplasmic reticulum and many different parts that help us make proteins RNA or make copies of our DNA.
2) Like I said before our cells contain many different organelles that have a specific function. The nucleus is the outer part of the nucleolus which stores our DNA. From here information is sent out to make proteins and RNA. Organelles are similar to our organs because they are smaller parts coming together to make a larger system function.
3) We all know there is connective tissue but one thing I didn’t know is that blood and lymph are also connective tissue. Smooth muscle tissue is found by you arteries but some smooth muscle tissue can also be found on you stomach!
4) Watching this video first made me think of our coast guard and think about what they do for us everyday to keep us their country safe. Also I learned how much there is to fly a helicopter and how many adjustments it takes just to keep the helicopter steady. By learning this I learned that it takes about 4,000 nerves to just mover our hand! All our nerves are transmitted through the brain at one point in time. I think how we teach ourselves to perform different things for example teaching our self to do a foot jam tail whip on a bike is really teaching our nerves what to do at what time and the repetition will help our bodies automatically remember what to do so we are able to perform with our eyes closed.
5) After watching this video I learned that we only use about a third of our muscles potential even when we are trying our hardest. I also learned that our muscle work y pulling and contracting the muscles are used as a lever against our bone. Adrenaline is what I think will help us use over a third of our muscles potential at one time.
1. The relationship between the human body, systems, organs, tissues, and cells; it’s like the ladder we did in class. The human body is made up of the 11 systems; the 11 systems are made from organs. The organs are made of tissues either smooth cardiac or skeletal. And the tissue is made up of cells.
ReplyDelete2. What I learned is that the nucleus is the only organelle that stores DNA. I also learned that mitochondrion is one of the sources for energy in a plant cell. How I think the organelles are like our organs is each organelle does its own part so the whole plant works just like the organs in our body if they each do their own part the human body works.
3. What I found are different types of connective tissue some are adipose tissue, cartilage, bone and collagen. Smooth muscles can be found in your eye, veins and attached to your hair. Also, mainly found in the stomach and intestines.
4. I learned that we need our nervous system even though we may not want to feel pain it’s important. We have pain so we know where something damaged and we don’t make the injury worse. Endorphins can kill the pain automatically by your body, if the pain gets really bad or you concentrate on surviving rather than the pain. Once you relax the endorphins stop working.
5. I learned from video 3 that bones will do all they can to protect your organs. Also, your bones are stronger than concrete. Half of our bones are soft so they can bend. Our bone cells are always being replaced. What’s so remarkable is that a thigh bone can withstand a ton. When running the pressure for me is 720 climbing is 360 jumping is 1080.
1. The human body is made of 11 basic systems. These systems all perform a function, whether it be absorbing nutrients or providing defense from bacteria. What makes up these systems are called organs. Organs generally do one thing, like the heart pushing blood through the body. Now, organs are really made up of tissues. These tissues are made up of similar cells, which is what the body is composed of at its most basic.
ReplyDelete2. The nucleus is where DNA is. The nucleus represents the brain in us. Mitochondria give the cell energy. The cell membrane is like the skin on the human body. It is a wall from things.
3. Bone is a connective tissue, as is cartilage. Adipose is too, it has fat cells in in, which also provide insulation. That’s why seals have to keep fat; otherwise, they’d get cold from the water! Smooth muscles, on the other hand, can be found in your bladder and your iris, the colored part of your eye.
4. Your nerves react almost immediately to things. For each of the five senses, nerves transmit messages to a certain part of the brain. Pain, however, is all over the brain, there’s no exact spot that you feel it. Endorphins are realized when you feel pain, which relieves the soreness or sting. Endorphins are probably the strongest painkiller, at over 200 times the strength of morphine.
5. Your muscles work by contracting or extending. Tiny fibers have filaments in them, which slide past each other, making the whole fiber, and thus the muscle, shorter. With your muscle, you can lift things many times your body weight. When I’m climbing, for example, I’m using about 400 pounds of force. Running makes you handle a lot more, at 800 pounds! Jumping, however, puts the equivalent of 1204 pounds on your joints. Muscles are one of the toughest materials in your body.
1. The relationship between cells, tissues, organs, and systems are that they all rely on each other. They’re like the Russian Nesting Dolls, where you open up one doll, and a smaller one is inside. You open up systems, you have organs, you open up organs, you have tissues, you open up tissues you have cells. Grouping together to make a bigger part of the body is the relationship they share.
ReplyDelete2. The organelle that holds the DNA for the cell is the nucleus. It’s the most obvious organelle in a eukaryotic cell. The organelle that provides the cell energy is the mitochondria. They are about the size of bacteria. The organelles are similar to the body’s large organs because they both keep the host (cell, body) functioning.
3. Some types of connective tissues are lymph nodes. Smooth muscle tissues are found on the walls of hollow spaces, like blood vessels, stomach, intestines, and urinary bladder.
4. The nervous system is an information super high way, and we have about forty five miles of nerves. The brain sends signals through out the body in fractions of seconds to make us move and feel. Pain is a defense of the human body. Pain alerts the brain when the body is damaged. There are different nerves for pain than for feeling. These nerves send the sensation of pain more slowly than the others. Pain signals don’t go directly through the brain, but through the spinal chord. The brain can suppress pain by releasing endorphins. They are more than two hundred times more powerful than morphine and make the feeling of pain gone.
5. We are born with every muscle fiber we’ll ever have. They just get bigger or smaller, but do not change in number. Muscle tissue works by contracting, pulling on the bone like a lever. Even when we’re exerting ourselves, we’re only using about a third of our muscle fibers at one time, but in times of extreme stress or danger we are able to use all of the power in our muscle fibers. When running there is 1308 lbs of force exerted. When climbing, there is 654 lbs of force exerted. When jumping 1962 lbs or force.
1. The human body is made up of eleven systems of the body. The systems in your body are made up of groups of organs; there are about 78 organs in the human body. The organs are made up of tissues and the tissues are made up of cells.
ReplyDelete2. I learned that the organelle cells that stores DNA is called the nucleus, the organelle that's responsible for the energy that a cell needs to survive is called a mitochondrion. Organelles are similar to organs because their purpose is for the cells to survive, and they all have different jobs to do this, and the organs' purpose is for the body survive and the organs all have different jobs to do this.
3. Three other types of connective tissues are called collagenous, elastic and reticular fibers.
Another place that smooth muscle is found in is the iris of the eye.
4. I learned from the second video that below our skin there are really small heat sensors at the end of nerves, our body produces sweat to cool our bodies down, and that when the body loses too much water the brain sends signals for it to suck the sweat back in.
5. From the first video I learned that muscles work by contracting and they use the bone they are connected to like a lever, each of your muscles is made up of thousands of fibers that are all bundled up together, inside of every fiber of our muscles there is small filaments that are also all bundled together and that most of us only use a third of our muscles at one specific time. When I am climbing, 300 lbs of force is put on my body, when I am running, 600 lbs of force is on my body and when I am jumping 900 lbs of force is put on my body.
1. I think the relationship between the cells, tissues, and organs is they all make up eachother. The tissues couldn’t be tissues without cells and the organs couldn’t be organs without the tissues. They all work together to make sure the body does what its supposed to and performs how its supposed to.
ReplyDelete2. The organelle that stores the DNA looks like the biggest part of the cell and is called the nucleus. It stores different characteristics for that cell. Telling it what to do and what not to do. The part of the cell that gives it energy is the mitochondrion. This part of the cell is the main energy part, the cells gets all of its power from it. I think that the parts of the cell are similar to body organs because they all work together to make the bigger thing function. And the human body can’t function without all organs working right and the cell can’t function without all the organelle working right.
3. Some other types of connective tissue would be ligaments and tendons. Ligaments hold bone against bone together and tendons hold muscles to bones. Other places smooth muscle tissue is found is in your organs. They move without you even knowing and you can’t control them!
4. Neural tissue to me is the tissue that tells you what to do! It has all your nerves in it and those tell your body how to act. Without it you wouldn’t be able to do anything!
5. Muscle tissue to me is the tissue that makes us strong. It absorbs all the pressure we put on our body every day and keeps us able to move around all the time! I put in my weight and when I run I exert 720 lbs, when I climb I exert 360 lbs, and when I jump I exert 1080 lbs of pressure. Its crazy and amazing to me how much I put my body through by doing simple things like climbing upstairs and I completely withstand it!
1. Cells are one of the smallest living things, in fact the smallest living item that comprises what we call our body. There are a couple hundred different types of cells, and when the join together to work on the same project, they're called a tissue. Tissues working on the same thing are called organs, and organs accomplishing something together are called body systems.
ReplyDelete2. The nucleus stores the genetic information, or DNA. Inside it is the nucleolus, where ribosomes, which build proteins, are made. Mitochondria are the "powerhouse" of the cell, giving energy so that the cell can accomplish what it needs to do. Organelles, as is evident by their name, are akin to the body's organs: they perform specialized functions in order to keep their host living normally.
3. Some other examples of connective tissue include cartilage (such as what is found in your nose and ears) and bone. Aside from arteries, smooth muscle tissue is also found in the bladder, uterus, and digestive tract.
4. I learned that pain is there for our own protection. The pain nerves carry the signal through the neural tissue, specifically the spinal cord, slower than other nerves: this is why a lot of times there is a delay between our injuries and when we start feeling the effects of them. The delay gives the brain time to see how much damage there is and figure out what it should do about it. Unlike other senses sending signals to the brain, which are processed in specialized sections of the brain, pain is felt in a much wider region. Endorphins are the brain's way of suppressing the pain, and they are able to suppress the nerves' signals by gumming up the "junctions" in between the nerves.
5. Muscles work by contracting - like levers. The tissue is made up of tiny muscles fibers, which in turn are made up of muscle filaments. Chemical signals call these filaments to action, which starts the muscle moving and working. While running 822 pounds of force is put on my body, 411 pounds while climbing, and 1233 pounds when jumping.
1. Cells are the basic component in the body. They get together and make up the tissues. Again, tissues get together and make up the organs. When the organs function, the system occurs.
ReplyDelete2. There are two types of cells. One is the animal cell and the other cell is plant cell. In both cells, nucleus stores DNA. It provides the cell unique characteristic. Mitochondria provide the cell energy to function and produce products. It’s an energy source. The organelles in the cell are similar to the body’s large organs because the organelles in the cell are working hard to make the cell function properly like the large organs.
3. Some other types of connective tissue are loose, dense connective tissue, and cartilage. Other types of smooth muscle tissue are muscles of pupil and muscles of arrector pili.
4. When the body gets warm too much, the nervous system sends a message to the brain. The brain reads the message and gives an order to the nervous system. The nervous system gets the order and starts sweating. Also the blood brings the heat and carries it to outside. But when the body sweats a lot, the body gets dry. So the nervous system stops sweating because we need moisture to live in the dessert.
5. Muscle tissue works by contracting, pulling on the bone. Each muscle made of thousands of individual fibers. They work together to make strength. Fibers get shorter and longer to move and that movement occurs the strength. They sometimes do incredible things that we normally can’t do. For example, when we are in a trouble that possible to die, muscle tissues make maximum strength to live and keep our body safe. When I’m climbing, it forces 414lbs. When I’m running, it forces 828lbs. Last, when I’m jumping, it forces 1242lbs.
The relationship in the human bodies between cells, tissues, organs, and systems are first that cells are very small particles in your body. They form into tissues when the cells begin to stick together and tissues form into organs when the tissues decide where they want to stay in the body and stick together. Lastly organs form systems by grouping together. That is how they are all related to each other.
ReplyDeleteThe organelle that stores blood is the nucleus. That is one of the facts I leaned from going to the website offered. Another thing I learned is that the mitochondria is the energy source for the cell and they are mostly known as the more dominant cells. The organelles are similar to your body’s larger organs because they both try to keep the cell alive. Those are just a few things I learned out of this website.
Some other types of connective tissue consist of are the loose connective tissue, adipose tissue, blood, collagen, cartilage, and the bone. Also another place a smooth muscle tissue is found in the walls of an internal organ.
What I learned about the nervous system is that the spinal cord is the main path it needs to take to send messages to your brain and those two work together to do so. Another thing I learned about the nervous system is that when your body gets really hot your nervous system starts to send signals to your brain to start your cooling mechanism and what your body does is start to sweat. Sweating is one of the best things your body does to cool off. Those are the things I learned.
What I learned about muscle tissue is that muscle tissue contracts and it works In a really small way and it treats your muscle as a lever. I also learned that our body only uses one third of its actual muscle strength. For climbing my body handles 384 pounds, for running my body handles 768 pounds, and lastly for jumping my body handles 1152 pounds. These are all the things I learned.
1. The relationship in the human body between cells, tissues, organs, and systems, in my opinion, is that the body is made up of millions of cells which form all the other parts to our body. Cells make up tissues, and tissues are made of specific cells that do things in a certain way and have a specific purpose, and those tissues make up a group of larger things in our bodies called organs, which are a group(s) of tissues together. Going a step above that, organs that function similarly make up systems because of the fact that they work together to accomplish the same thing. Without cells, we would not have our body tissues, which would mean no organs, and also, no body systems, which would mean us not functioning right.
ReplyDelete2. The nucleus of a cell is the organelle that stores DNA. The energy source of a cell is the organelle mitochondrion. Organelles are similar to our body’s large organs because our large organs carry out specific functions and have a purpose and job to do, and without them, we could not live well, and just like the organs, organelles each have their own job and purpose, and without one of the organelles, the cell would not be able to carry out its function properly.
3. Some other types of connective tissue would be bone and also cartilage. Other than being found in the arteries, smooth muscle tissue is also found in your veins and stomach.
4. I watched the second video, and from that I learned our bodies can withstand heat up to 93 degrees and after that point, the heat sensors in our nerves that are throughout our body will send messages to the brain telling it that the body needs to cool down, and the brain reacts to that by sweating. I also learned that after a long period of time in the heat, and when our bodies become dehydrated, the brain will then tell the body that it needs to stop sweating to save all the water and moisture for the organs to continue working.
5. In the first video, I learned that muscles use our bones as almost like a lever system. The muscle contacts and releases to move the bone which moves the body parts. Also, we are born with all of our muscle fibers, but in our lives, we will only use about a third of them during a certain point, which means, that if needed, our body can have tremendous strength and power. On the force scale, there is 459 pounds of force put on me when I climb, 918 pounds of force when I run, and when I jump, there is 1377 pounds of force on me.
The Human Machine
ReplyDelete1.The way that cells, tissues, organs, and body systems are the same is that they are all made together. By that I mean that a cell is a part of a tissue, a tissue is a part of an organ and so on. Soon they become a body system and then the body. Really all of them are of the same composition.
2.The organelle that stores the DNA, which is the Deoxyribonucleic acid, is the nucleus. This DNA is what give the cells in the body its characteristics and effects the characteristics of you. The mitochondria is what provides the cells with their energy. And all of these organelles relate to the body’s organs in that they all work together to keep us alive.
3.Some other types of connective tissue are; blood, collagen, cartilage, and the bone. These might surprise you but if you think about it they all connect things in your body together. You can find smooth muscles in more than the arteries; you can also find it in the bladder, the reproductive tracts, and even the eye.
4.The body is constantly sending signals al around the body to keep us alive and things like our body temperature getting to hot. Our body would cook if we did not have the nervous system. Once our body is too hot the nerves under the skin send signals to the brain that tell the body to release what we call sweat.
5.We owe all of our movements to the muscles in our body. To move the fibers in our muscles contract and rub together which make us move. Because this is such a simple movement we are able to move things more than twice our weight. I weigh 199 pounds, the weight used in climbing: 597 pounds, running: 1194 pounds, and jumping: 1791 pounds.
1) The relationship between cells, tissues, organs, and systems is: cells are in and make up everything in the body, tissues are groups of cells, organs are groups of tissues, and systems are groups of all of these put together to make the body function.
ReplyDelete2) The nucleus stores DNA. The mitochondria is the energy source for the cell. Organelles are similar to large organs because they’re both required for the body to function properly.
3) Some other types of connective tissues are cartilage, bone, and blood. Smooth muscle tissues are also found in the skin and the iris of the eye.
4) Immediately after you get injured, or experience pain, your nerves send messages to the brain letting it know. Pain nerves carry their signals slower than any other signal. That is why there is a small delay between injuring yourself and actually feeling it. Certain senses have certain parts of the brain that retrieve those signals, whereas pain is a sensation that occurs all over the brain. Pain is the only sensation where that signal has to ‘jump’ from nerve to nerve. When your body doesn’t want to feel pain, it sends out endorphins to cover the nerve endings. This is 300 times more powerful than morphine.
5) Muscles pull at the bone, using it as a lever. We are born with every muscle fiber that we will ever have, even if our muscles get bigger or smaller throughout our life. To move the muscle, filaments must lock together. At one time, we only use about one third of our muscles’ fibers. When we are in danger or shock though, we are capable of performing tasks that we wouldn’t normally be able to do. Much like Sinjin, heaving a 1200 pound rock over a cliff. Climbing: 405 lbs., running: 810 lbs., jumping: 1215 lbs.
1. Explain in your own words the relationship in the human body between cells, tissues, organs and systems.
ReplyDeleteCells make tissues and tissues make organs and organs make system that looks like gear wheel. Cells, tissues, organs, and system form human body.
2. Click on the hyperlink on the word "cell". Go to the website and learn simple things about the different organelles. Which organelle stores DNA? Which organelle is the energy source for the cell? How are the organelles similar to your body's large organs?
Nucleus has DNA. Mitochondria is the energy source for the cell which is ATP. Organelles have function which means organelles have part looks like large organs.
3. Name some other types of connective tissue. Upload a photo in your comment of a type of epithelial tissue. Where else is smooth muscle tissue found aside from arteries?
Epithelial tissue and muscle tissue and neural tissue and blood and lymph is other type of connective tissue. We can find smooth muscle tissue at blood vessel like aorta.
4. Click on the link "endlessly difficult to understand" right above the snowflakes. This will take you to a website. Click on sensation and watch one of the three videos. Describe in your own words what you learned about the nervous system/ neural tissue.
CNS(central nervous system)is include brain and spinal cord. Peripheral nervous system connect central nervous system. Automatic nervous system is different path of Peripheral nervous system.
5. On the same website, click on Strength. Watch one of the three videos. In your own words, describe what you learned about muscle tissue. Then, look at the diagram to the left and enter your weight. How much force is put on your body when running? Climbing? Jumping?
Muscle can make to move and exercise. Muscle can hold something. Muscle protect us from danger. When I am climbing there is 324 lbs. when I am running there is 648 lbs. When I am jumping there is 972 lbs.
1)My thinking about cells, tissues, and organs is that each of them are very important to our bodies. Cells help form tissues without cells we wouldn’t have anything. That just goes to show that even the small things matter in life. Without tissues we wouldn’t have organs and without organs we physically couldn’t live. Organs also play a huge role in every system of the body. They are what keep the body functioning and make life sustainable.
ReplyDelete2) The nucleus is where DNA is stored. Then for energy storage we have the mitochondria. Organelles help the body function just as cells help the body function. Each cell has a certain classification as do organelles. So they pretty much go hand in hand.
3) Different types of connective tissues would be epithelial tissue, neural tissue, and muscle tissue. Smooth muscles can be found not only in arteries, but also in the bladder.
4) I learned that there is over 45 miles of nerves within our bodies. That’s pretty cool because that’s not something we really think about on how something so small could be so long. I also learned that the nerves can be up to 2 feet long, and that nervous are insulated with fat. That’s pretty cool how two things in our bodies come together to form something so useful and so cool.
5) After watching the video I learned that when in shock the muscle tissue shifts into “overdrive” which differs from normal. When muscles are normal we use maybe 1/3 of them. But when in certain situations when muscles switch into “overdrive” they become much stronger and are able to push the boundaries that normal muscle tissues could reach and are able to do much greater tasks. And when running the force put onto my body is 840 pounds, when climbing its 420 pounds, and when jumping its 1260 pounds! Just goes to show how strong our bodies really are!
1. The difference between all of them is that the organs are in the systems and the tissues are part of the organs. Then the cells are part of the tissue. System: group of related organs (Total Health Boe, Susan). Organs: 2 or more tissues grouped together and they perform certain functions (Total Health Boe, Susan). Tissues: made up of similar cells that are specialized to carry on functions (Total Health Boe, Susan). Cells: basic building blocks from which all larger parts are formed (Total Health Boe, Susan).
ReplyDelete2. The nucleus is responsible for storing DNA. The DNA is the same in every part of a cell but some genes cannot work and some can work. The organelle that is the energy source is the Mitochondria. They are similar because the organelles are small organs and they each have a specialized function.
3. Some other types of connective tissues are Epithelial tissues, muscle tissue. Blood and lymph are other types of connective tissue in your body. Smooth muscle tissue is found in the aorta along with the arteries.
4. I learned in the third video that if we don’t have pain it can’t tell us when something is wrong with us. The pains goes up your spinal cord and into your brain which then allows us to feel the pain from the injured area that needs to be healed. If we didn’t have this process in our body’s we wouldn’t be able to know when our bodies were hurt and needed to be healed because we wouldn’t feel anything wrong with our body’s.
5. Muscles work by becoming shorter and then becoming longer which allows us to move. In extreme danger we are able to do things that would normally be impossible but because of the adrenaline in our body’s we are able to move they even though we couldn’t do anything near this amazing without the adrenaline. When I am running there is 1080 lbs. of force on my muscles, when I am climbing there is 540 lbs. of force on my muscles, and when I am jumping there is 1622 lbs. of force on my muscles.
1. The relationship between cells, tissues , organs , and systems is that in cells there are already organs in them, these organs are called “organelles”. These organs make our body operate (work).
ReplyDelete2. The organelle that stores DNA is the Nucleus; which makes the unique characteristics of the cells. The organelle that is the energy source for the cell is Mitochondrion. The organelles are similar to our body’s large organs because they have an important role in the body to make it function correctly.
3. Some other connective tissues are Muscles tissues and Epithelial tissues. Smooth tissues are also found in the aorta.
4. What I learned from the nervous system/neural tissue in video 1 was that we have millions of tiny sensors that pick up millions of sensations from the world around us and carry the sensations to our brain ( like pain or just feeling something touch your hand etc.). Our nerves are long thin cells, some of them are around 2 feet long sending signals to the brain.
5. What I learned about muscle tissue in the first video was that muscle tissue works by contracting and pulling on the bone and using this as a type of “lever”. These contractions are microscopic, each muscle is made up of thousands of individual fibers. When they contract the muscle fibers get smaller. When exerting we usually only use about one third of our muscle. In each fiber there are smaller filaments. When your body is sent into overdrive it depends on only the power in your muscles like your arm muscles, chest muscles and stomach muscles. We are born with every muscle fiber we will ever have in our life. There is 285 pounds of force while climbing. There is 570 pounds of force while running and there is 855 pounds of force while jumping.
1) Our cells make up tissues, tissues make up organs, organs make up systems, and the 11 systems make up the body.
ReplyDelete2) The Nucleus stores the DNA. The Mitochondrion provides the energy for the cell. The cells are like the major organs because they all have their purpose. Without all these organelles the cell would not be able to function properly.
3) They are ligaments and tendons. Smooth muscle tissue is also found in the urinary bladder, uterus, male and female reproductive tracts and the respiratory track.
4) I learned that our bodies will do just about anything to keep us alive. Like in the 2nd video the body stopped sweating, took the moisture out of the eyes and tongue, and it put water back into the lungs, liver, and heart. I also learned that the pain suppression hormone is 100 times stronger than morphine.
5) I learned that we only use about 33% of our muscle’s full strength at one time. In time of danger our muscles can lift something very large. In extreme danger our muscles will destroy themselves to protect us and sometimes, we will be able to use the full strength of our muscles. When we are born we have all the muscles we will ever have. Our muscles use the bones as levers to help us lift things. Muscles are made up of wires and when used they bind together like cables. In each fiber there are smaller filaments. When muscles are used they band together, as they slide past each other the muscle gets shorter. These contractions are responsible for our movement. When I’m climbing I put 459 lbs of force on my body. When running, I put 918 lbs of force, and when jumping I put 1377 lbs of force on my body.
1. The relationship between cells, tissues, organs and systems is very unique. They are all connected to each other in some way and help our body function properly. Cells are the building blocks for our body and contain many smaller parts. Cells then group together to do a specific function and they make up tissues. Tissues are everywhere in our body. Cardiac muscle is in our heart, Skeletal muscle is located around our bones and smooth muscle is in our arteries. We control some muscle tissues and others function every second of every day without us controlling it such as our heart. It beats and we don't have to think about it. When multiple tissues perform similar jobs they group to make organs which then group to be systems. Our body is made up of eleven systems which help us survive each day.
ReplyDelete2. The organelle that stores DNA is the Nucleus. The energy source of the cell is the Mitochondria. They are about the size of bacteria.Organelles are similar to our bodies large organs because they perform specific jobs. Such as the Lysosome is responsible for the digestion in plant cells, the Secretory Vesicle is located in the Golgi apparatus and it secrets horomones, and the Cell Wall is like the plant cells skin. It protects the outer part of the cell.
3. Some other types of connective tissue is bones. Bones are mineralized connective Tissue. Calcium Phospahte is what gives bones its firmness. connective tissue is also located in vertebrates. The most common type of connective tissue is loose connective tissue. This hold organs in place. An example of loose connective tissue is Adipose, which stores fat.
4. I learned when our skin gets to ot we have a cooling response which is sweat. This is the most efficent way to cool our bodies down. Nervous system is fourty five miles. Our brain is faster at processing instruction then any computer on the planet. Some of our nervous can be up to two feet long. They are like electrical wires, insilated by fat. Pain is one of our bodies defenses. Pain is a mystery when it comes to our nervous system. Pain alerts the brain the body has been damanged. It fires signals into the nervous system but they are slower then other signals which is hy there is often a delay between injury and actual pain.
5. 390 pounds of force is put on my body when climbing, 780 pounds when running and 1170 pounds when jumping. We are born with all our muscle fibers and it is up to us to make them bigger or have them stay small. Contractions are what cause us to move. We only use about a third of our muscles. Fat stores energy. The wall is when your body runs out of energy. Normally you can go two or three hours before you fell fatigue and "hit the wall". The body will feed off its own fat in order to make new glucose (sugar) but we never fully lose those cells they just become bigger or smaller. All of our muscles need fuel, glucose, and the more we train the easier the "task" is, being a swim such as paul or running.
1. A cell is a single unit of organism. when many cells form together, tissues are formed. so when loads of tisssues come together, organs are formed. and when organs work with other things in our body, a system is formed.
ReplyDelete2.The neucleus. The Mitochondria. Organelles help keep the cell alive.They are surrounded by membranes.Each type of organelle has a specific function that helps the cell.Several kinds of organelles are suspended in the cytoplasm. Organs help pump blood to all parts of your body.
3. Epithelial: Occurring in sheets of tightly packed cells. Covers the outside of the body
Simple epithelium : consists of a single layer of cells.
Connective: Functions mainly to bind and support other tissues. They contain a sparse population of cells surrounded by a nonliving matrix. This matrix can be fibrous, liquid or jellylike.
Elastic: Made of protein called elastin. These fibers are very resilient and as rubber snap the structure back after it has been moved
Smooth muscle can be found in Lymphatic vessels, the ciliary muscle, and iris of the eye
4.What i learned from watching the video is that the neural system is a high speed highway for informtion that goes to our brain and sends electric sinal back almost instantly,Also that there is about 45 miles of nerves.Our nerves are thin cords that travel at high sped carrying electrical signals they can only travel that fast because they are insulated by a layer of fat.
5.What i learned about the muscle tissue is that Muscle tissue works by contracting, pulling on the bone and using it like a lever. Each contraction takes place at a microscopic level. When climbing i put 705 lbs of force on my muscles. When running i put 1410 lbs of force on my muscles. when climbing i put 2115 lbs of force on my muscles.
1. In the human body there are cells, tissues, organs, and systems. They all are related. For example in school, the cell could be the brain of the student, then the tissues are the students, the organ is the teacher, the system is the principal, and then the school is the body.
ReplyDelete2. The organelle that stores the DNA is the nucleus. The nucleus is where the cell gets and gives its characteristics. The organelle is the energy source for the cell to move, called the mitochondrion. Organelles are similar to your organs. The organelles are your cell’s organs and they both help the bigger function to work.
3. Connected tissues are fibrous connected tissues that are in the tendons and bands of tissues that hold the organs in place. Some other types of connected tissues are epithelial, nervous, and muscle tissues. The smooth muscles are located on the insides of inner forms of the stomach, intestines, and urinary bladder.
4. What I learned about the nervous system/ neural tissue in the video with the man and his daughter in the desert; is when your body gets too hot it begins to sweat. The brain gets the message to sweat. Sweating is one of the best ways to cool off. When the body gets too hot and does not get the water that is needed, it gets dehydrated. Then your body absorbs the sweat back inside because it needs water to work.
5. When you exercise you need a lot of carbohydrates and fat because they both give you energy. When you feel like you are going to give up and your body gets tired that is when your body eats itself in a way. That is good because it gets ride of your fat cells. The results I got on the diagram are the forces that I use on my body. When I am climbing I use 330 pounds, when I jump I use 990 pounds, and when I am running I use 660 pounds.
Our bodies are truly amazing things, when you look closely at them you see tiny cells. These cells alone are not much but single living things, but together form a small cohesive squads called tissues. These tissues can be many things, they can be muscle tissues, connecting tissues, tissues that make up outer layers of your organs, or even nerve tissues. These tissues then come together to join one cohesive unit called an organ and do work to better your body. Then similar organs join forces and form 11 bodily systems to act even better than before.
ReplyDeleteA cell, what is it exactly? Is it alive, and what is it composed of? A cell is composed of a ton of tiny little things called organelles. The nucleus is the brain of the cell, it communicates to other organelles and also holds the cell's DNA, or genetic structure. Then there are the mitochondrion which are the power source of the cell. They provide energy for the cell to do what it needs to do and work as it needs to work. Organelles are in many ways not much different from our own bodies organs. Just as organs work together to better the body, so organelles work together to better the cell.
There are many different connective tissues, there are ligaments, blood capillaries, and nerves just to name a few. There are also those muscles that beat on their own, which are called smooth muscles. They include the heart, lungs, and eyelids.
They nervous system receives messages from nerves in the arms, legs, and other senses and send them back to the brain. Then within a split second the brain tells these organs exactly what to do! This is a truly amazing feature of our human body.
Our muscles are truly the brunt of our bodies. They are full of small interlocking tissues called fibers. By contracting our muscles we can propel ourselves forward, lift objects, or jump super high. For me when I am running I put 900 pounds of pressure on my body, when jumping it is 1350 pounds of pressure, and when climbing it is 450 pounds of pressure! Our muscles are another amazing part of our bodies!

ReplyDelete1 Cells, tissues, organs and systems what they do in my words. My thought on these is that they all make up one big system called the human body. Each system has a special job to do to make the human body work.
2 Cell learning I found. Well I knew from 8th grade about the animal and plant cell. Cells are super small like the size of a dust mite or head of a pin. The organelle that stores DNA is the Nucleus. The organelle that is the energy of the cell is the Mitochondria. Organelles are similar to our body’s larger organs because they both have an important part in the body to make in work. There like smaller organs in a way.
3 Some types of Connective tissues. Some other ones are epithelial tissues, nervous tissues and muscle tissues. Another place the smooth muscles are also found in the aorta and or uterus.
4 Nervous system leanings. What I learned everything you do you have a feeling to stuff. When the one lady fell 60 feet her nervous system went right into action and she felt everything that happened and that had to be pretty pain full for that to happen. When you feel something that doesn’t feel goo a message gets sent to your brain that pretty much says don’t touch that anymore and the message gets sent from your finger up to your brain.
5 Strength learning. I learned that the food you last ate turned into glucose and that what keeps people going when they are burning off that energy. The human body has about 2 to 3 hours of energy. I learned that the human body can go a long time with food energy it gets from foods. When I am running there are 510 strains on my body, jumping there are 1,020 strains on my body and, climbing I am putting 1,530 pounds of strain on my body.

ReplyDelete1] Basically cells make up tissues. Tissues make up organs. Then organs make up systems. So you can almost see already how they relate. Pretty much it is building blocks for our bodies from smallest to biggest.
2] The nucleus is responsible for storing DNA in a cell. The mitochondrion is responsible for the energy a cell needs. The organelles are similar to the organs because it seems that each of them have a particular function just like our organs.
3] Some other types of connective tissues are blood and lymph tissues. Smooth muscle is found other than in arteries in the bladder and the digestive tract.
4] I watched the sensation videos. The nervous system has millions of extremely small heat sensors that tell the brain if the skin temperature rises above 93 degrees. Your brain then tells you to start sweating. But if you are dehydrated too much then you won’t sweat. Pain alerts the brain when the body has been damaged. Any injury causes chemical reactions inside the brain. Pain nerves carry signals slower than other nerves in the body. The reason that there is sometimes a delay between feeling pain and getting hurt is because the brain is assessing the damage. Senses such as sight hearing or touch are felt in certain areas of the brain but pain goes everywhere in the brain. When pain happens the nerves tell the spinal cord first which then tells the brain. This is how the body can suppress pain. The brain tells the spinal cord basically to shut up.
5] I watched the third one. Your body can exercise at the beginning just going of fat or glucose but pretty soon you will get tired. The average person has two to three hours worth of energy then they feel like they want to quit. If we keep going our body will start eating itself. The body never loses or gains fat cells. 900 pounds of force is put on my body when running. When climbing I have 450 pounds. When I jump 1350 pounds of force is put on my body.
1. The cells are the smallest part of our body, and they work together to make tissues. The tissues work together and make organs, which are parts of the systems of our bodies. So the cells form to make other things which eventually make the eleven systems.
ReplyDelete2. The organelle that stores DNA is the nucleus, and the organelle that is the energy source for the cell is the mitochondrion. The organelles are similar to the body’s organs because they work together in different ways to perform different tasks, they all have different functions.
3. Different types of connective tissues are tendons, bones, cartilage, the ligaments around joints, and blood. Smooth muscle tissues could also be found in your veins and capillaries as well as arteries.
4. I watched the first video, and I learned that we depend more on our nervous system than we know. We send signals to our brains and it sends them to the rest of our body, and we cant feel this happening. We are able to multitask in many ways thanks to our nervous system helping our body move in the way it is supposed to, because without it we wouldn’t really be able to do anything.
5. I watched the tornado video, and I learned that the bones are made to protect our organs from being damaged. The guy who was swept up by the tornado would have been dead if it weren’t for his bones protecting him. The cells in our bones are hollow, causing them to be very lightweight, and most of the bone is soft, so its able to bend. When I’m climbing, 360 pounds of force is put on my body; when I am running: 720 pounds, and jumping: 1080 pounds.
1.Each part of the cells, organs, tissues, and systems has an important role in making up the other parts. Cells are the smallest group. Cells can group together to make tissues. The next group is tissues which group together to make organs. These organs run together to make systems. Organs also make up the cells which are called organelles.
ReplyDelete2.For organelles the one that stores DNA is the Nucleus. The mitochondria are the energy source of the cell this energy made here is called ATP. This is also called the powerhouse of the cell. The organelles are part of the system. They all have jobs in the cell to help it function properly. Just as the organs in our body all have their unique parts in a system.
3.A few other types of connective tissues in the body are muscle tissue, epithelial tissue and neural tissue. Two other types of connective tissue in the body are Blood and Lymph. A few other examples of where smooth muscle would be found are in besides the arteries are the skin, respiratory tract, and urinary bladder.
4.I learned that the nerves have a fat layer in which surrounds the nerves like a sleeve. Also, there are about 4,000 neurons running through our body. The average nerve cable is about two feet long.
When we get our bodies in extremely bad situations our body starts seeing we need a lot of extra energy so it goes into an adrenaline rush state.
5.Muscle tissue works by contracting, pulling on the bone to use it as a level. These contractions take place so small it’s at a microscopic level. At 132 lbs. which is my body’s weight, my body handles about 396 lbs. every time I go climbing. When I go for a run my body has to handle 796 lbs. If I am going to jump or just merely jump rope my body handles 1188 lbs. of pressure.
1. The relationship between cells, organs, tissues, and systems in our body is like a string of lights- connected together. With every part functioning properly, they maintain a healthy and balanced “machine:” you. Cells and organs that work together are called organelles. See? It is like a combination or relation of “organs” and “cells.” In a chain reaction, formed cells connect to tissues, and organs eventually come together to form a well- functioning body system for you to live a healthy lifestyle.
ReplyDelete2. The organelle that carries DNA is called the Nucleus, and the Mitochondria is the cell’s source of energy. Organelles are similar to our body’s larger organs because even though organelles are much smaller than the large organs in our body, they each play a vital role in maintaining the healthy balance of our body’s functioning.
3. Some types of connective tissues listed are neural tissue, epithelial tissue, and muscle tissue. Neural tissue is like a voice box in your brain that tells the rest of the body and its parts what to do. Epithelial tissue is made up of organs that are “soft organs” such as your heart and liver, etc. It also is what makes the skin on your body! Muscle tissue is like the building blocks for your muscles- both muscles you can control and even muscles you can’t control. It is made up of three parts: smooth muscles, cardiac muscles, and skeletal muscles. Smooth muscle tissue is found in the arteries but it can also be found in the aorta.
4. In the video I watched, I learned about pain. Pain is definitely a feeling we do not enjoy, but it is very important in our nervous system. When we get hurt or injured like Amy was in the video, our body triggers the pain where the injury occurred and sends messages up to the brain. Pain signals in our body act like body guards on guard and ready to take action. They move slowly, but when we get injured, they rush up to the brain. That is why it is said that pain is not an instant sensation after occurrence but a short second after it takes place. As sight, touch, memory, or other senses are about certain parts of the brain, pain flows throughout the entire region! So as painful and troublesome as injuries and pain itself can be, it is so good and very important to have it.
5. I learned that our body’s bones act as a shield to our internal organs so that they cannot be injured by harmful occurrences such as Matt’s case. He was thrown on the ground by a tornado that had sucked him up into it, and yet managed to keep every bone in his body from breaking. Our bones are said to be stronger that concrete itself! The inside of our bones is hollow, and the walls are as thin as a sheet of paper. The marrow and other substances in our bones are living and reacting to what we do every day. We can replace every bone cell in our body in a span of seven years! The amount of force I put on my body while running is 375 lbs.; when running, I put 750 lbs. of force on my body; jumping put 1125 lbs. of force on my body.

The relationship between the cells, tissues organs and systems is, a cell unit of an organism. Tissues are formed when many cells form together. When a lot of tissues group together organs are formed. Then when organs work with other things in our body a system. So all the parts together form one system.
The organelle that stores our DNA is the nucleus. The nucleus is the most obvious organelle in any eukaryotic cell. The organelle that is the energy source for the cell is the Mitochondria. Like your large organs, organelles in the cell each have a unique biological role to play in the human body.
Some other types of tissue are loose connective tissue, adipose tissue, blood, and collagen, sometimes called fibrous or dense connective tissue, cartilage, and bone. Here are some definitions loose connective tissue is a mass of widely scattered cells whose matrix is a loose weaves of fibers. Adipose tissue is the adipose cells in the loose connective tissue. Bone is a rigid connective tissue that has a matrix of collagen fibers in calcium salts.
I watched the first video and this is what I learned. There are 45 miles of nerves in the human body. We can process a lot of information. In the video mat uses 4000 motor nerves to drive the helicopter with his hand. Nerves are long thin cells that carry electrical signal t and from the brain. Nerves are insolated by a layer of fat like electrical wire.
I watched the video with the rock climber named Singen who was trapped under a rock that weighed a lot, and when he was about to go off the edge he threw it off. Muscle tissue works by contracting and pulling on the bone. They take place at a microscopic level. Each muscle is made up of thousands of individual fibers bundled up. We are born with every muscle fiber will have. Within each fiber are filaments.

There is a relationship between cells tissues organ and system in the body. The reason why there is a relationship between all these things is because they are made up of each other. Cells make up tissues and tissues make up organs and organ obviously make up systems they are all connected to each other and they build off each other.
The nucleus stores the DNA of a cell. Mitochondrion stores the energy of a cell. The organelles are similar to the large organs of the body because they have the same function but they are just way smaller than the large organs of a body.
Loose connective tissue is a type. Blood is a type, bone; adipose tissue, cartilage, and collagen are all types of connective tissues. Smooth muscle is found within the walls of blood vessels.
I watched video number 2. It is amazing that you can be out there that long in the heat without dying. The nervous system try to cool you down using sweat then once you sweat out almost everything it send messages to the body to suck the water back into for the heart and everything. This system keeps you alive as long as it possibly can. The dad and the daughter were trapped out in the dessert with temperature well over 100 degrees and they were 30 miles away from civilization. The miraculously made it back alive the human body is a amazing thing.
The video I watched was the second one. It is amazing that a tornado picked him up and dropped him a half mile away from his house. He did not break anything! I didn’t know that pound for pound bone is stronger than concrete! Half of bone mass is soft and alive! Our bones are constantly being renewed. A runner grows stronger leg bones than a swimmer. When you are knocked unconscious you bones are stronger. When I climb I’m using 495 pounds of pressure. When I run I’m using 990 pounds of pressure and when im jumping im using 1485 pounds of pressure.

The human body is a complex machine made up of cells that form tissues, organs, and every system. I think that cells are the most important because the cell it the basic block to form the tissues, organs, and systems. Cells make up tissues; together tissues form organs, and organs make up the 11 body systems. There are four types of tissue: connective, nervous, muscle, and epithelial. Each type of tissue groups up to form your organs. For example, without your nervous tissue, or neural tissue, you would not have organs like your brain or spinal cord.
ReplyDeleteThe cells in our bodies have many different types of organelle. There are around 15 kinds of organelle in a single cell including: golgi, the nucleus, cytosol, membranes, and endoplasmic reticulum. (fun to say☺) DNA in a cell is stored in the nucleus. The DNA in each cell depends on that cell’s function, but is mostly similar in all cells. A cell’s energy comes from the mitochondria. The energy that makes a cell move and perform its duty is sugar and oxygen. The organelle are like main organs in your body because they each have a function. Some organelle have tubes like the heart. The cells make up the organs in your body.
Honestly, I found that the connective tissue is very confusing. The easiest concept I found was that there are proper, special, and supporting connective tissues. The proper connective tissue includes loose and dense which can be regular or irregular tissues. Connective tissue with special properties are adipose which is fat, elastic, hematopoietic which is lymph nodes and bone marrow making red blood cells, and mucous which is like mucus. Lastly, the supporting tissue is cartilage and bone. Smooth muscle is found in the stomach, intestines, and blood vessels.
I watched the second video and learned that your body sends amazing messages. Your brain can tell the body how to work and stay alive in crazy situations. I learned that when you are dehydrated and in extreme heat, your body takes the water from your mouth, eyes, and you stop sweating. The body takes all this water and brings it to the heart and brain so you can continue to function. When this happens your blood vessels thicken. I also learned that if you bury yourself, you would stay cool.
I found video two very interesting. Our bones are very flexible and strong! The femur can stand up to about a ton of pressure before breaking. The man that was in a tornado was limp; this made the pressure on his bones even and kept him from breaking any bones. I learned that your bones adjust to fit your life style. The video said that a tennis player has bigger bones in their racket arm. The force when I am climbing is 321 pounds. When I am running the force is 642 pounds. The force when I am jumping is 963 pounds.
1. The relationship between cells, organs, tissues and systems, is that they all work together to keep the body functioning properly. They all work different parts of the body, but together, make everything work. Without most of all these things, we would not be able to function at all. Let alone properly.
ReplyDelete2. The cell’s organelle’s are similar to the human body’s organs because they all have a separate job or function that they do best and when they are put together they create something larger. The Nucleus stores DNA within the cell. Mitochondria is the organelle within the cell responsible for storing the cell’s energy and enabling it to move. Everything within the cell works together to make a cell and to keep it functioning properly, just like all the body’s large organs work together to keep the body functioning properly, too.
3. Besides being found in arteries, smooth muscle tissue is also found in the body’s blood vessels and veins. Some other types of connective tissues are tendons, the connective fibers surrounding the muscles, and the ligaments and capsules surrounding the body’s joints.
4. I watched the second video and I learned that are a bunch of little tiny nerve endings and tissues underneath your skin. They know when our body temperature is not normal, and sends signals to the brain. The brain itself knows how fix it and then regulate the temperature. The brain also tells the body to sweat, which is the best way to cool our bodies. However, if we run out of water< our blood thickens causing the heart and lungs to beat and keep the body cool.
5. I watched the second video on “Strength” and learned that our bone mass is made up of tiny pores that are alive. They are harder than concrete. They are also spongy and soft on the inside, not just a hard mass. Also, I learned that bones are flexible. I did not know that before now. There is 330 pounds of force on my body when climbing, 660 pounds when running, and 990 pounds when jumping.
1. Organs, cells, and tissues are related because the cells make up the tissues and then the tissues continue to make your organs and then pretty soon you have the human body.
ReplyDelete2. The Organelle that stores the DNA is the Nucleus. Then the Organelle that gives a cell the energy is the Mitochondrion. These Organelles are similar to our organs because they do the same things for plants and animals as they would do for our own bodies.
3. The epithelial tissue, the neural tissue, and the muscular tissue are the other 3 main tissues. Smooth muscles can also be found in the digestive tract.
4. What I learned is that our nervous system can process up to 1 trillion instructions per second. Under pressure our nerves can work in overdrive.
5. Muscle tissue is very flexible and can withstand many things. When climbing 570 lbs is exerted, 1140 lbs. when running, and 1710 lbs. when jumping.
