Immune System

Immune System

Function: The function of the immune system is to get rid of disease,viruses,and illness from the body.

Organs: The organs are the Tonsils,Thymus Gland,Spleen,Lymph Nodes, Lymphatic Vessels, Moucos Membrane in nose, throat, bladder and genitals. Then there is the Bowel, bone marrow and skin. Phew that's a lot. Of course im not going to bore you with the detail of them all. All you must really know is they all hold the same purpose. There purpose is to protect us from disease illness and bacteria. For example the bone marrow. This is where the white cells are made. The white cells are what is sent in the body to fight against anything that could harm. Then you have the lymph nodes. The lymph nodes make lymphocytes. Those are also white blood cells. Yep there pretty important.  Think without them our body would be corrupted with loads of disease right now with them.

Interaction with other systems: It works extremely close with the circulatory system.  The circulatory system is how all these important white blood cells get around your body to fight off these bad things. Without each other things would be very bad. You see the immune system uses the circulatory system to help the rest of the body. Then without the immune system the circulatory system would slowly die off with the rest of the body.


Analogy: The white blood cells are like soldiers. The white blood cells go out and fight for the bodies health. Just like soldiers. Soldiers instead fight for there country. You can kinda think of your body like that to. It is like a country. It is the big scale of everything to

everything inside.This why the white blood cells are just like soldiers. So we can live another day!


Structure and Function: The glands are shaped placed and sized the way they are for a reason.  The shape is special for its placement. The shape of the gland is right under your jaw. This means that it is fit the rest under our jaw line. It fits into a perfect slot between your law and your neck. Placement is important. Being placed need your brain is deter mental to the flow of white blood cells. Blood moves to the brain all the time. This makes it so the white blood cells can just be dropped of in that consistent flow of blood. Then last but not least size. The size of the gland must be small. You dont want them to be big because bigger means more production of white blood cells.  Yes it is good to have white blood cells but we dont want them to fill up the entire blood stream. You also dont want them to be too exposed since they are a huge central to health in the body. All this makes it so it can function the way it must to save us.

Cell Division And Cells to Organisms

Summary:  You are filled with cells. Now think how did you get to that point. How did you get organs and tissues. There is an answer! Cell division. Cell division in the process where one cell becomes two cells. Disclaimer NO cells were hurt in this process. Now how is that so? How can a cell just appear out of another? Well you see  there are 2 main steps that make this possible. Mitosis and Cythosis. The best way to think of Mitosis is as the Ctrl C and V part of this process. This makes sure the first cell doesn't just keep on ripping apart like a paper. This step also makes DNA. Yep DNA is the map of everything your made up of. You can kinda think of yourself as a building and the builders (cells) are using our blue prints to make you. Now there is Cytosis. Cythosis is the part where it stabilizes the new cell. It also starts adding in the nucleus and prepares it for the cycle to start over again.

S&EP: This week I  constructed explanations and designed solutions.  This week we did the cell division flip book. In this flip book we had to make the stages of cell division frame by frame. You can kinda think of it like stop motion. You can't make your pictures all over the place because your watcher will get lost and it would be jumpy. You also can't make it too slow because it will never move fast enough. We did have to use that happy medium to make the motions it goes through as best we could. If you were to look at the book you would learn a lot more about it and it could explain a lot about the topic. So this week we had to explain using this art flip book to help make others and ourselves better understand.

XXC: Systems and system models: This one was a no brainer. So for about 2 days this week we have been reviewing body systems. What are these systems you ask. They are groups of organs thats work together to complete a task such as digestion of breathing. These systems all help improve/ make possible our lives. These systems don't just come out of nowhere though you must start of with a group of cells. These groups of cells are all the same so they team up as tissues. Now that we got multiply tissues of the same function we get an organ. This organ performs a certain function then we start linking together and make a organ system. You get it now. Our bodies are full of systems and without them we could not function.

Cell Multiplication And The Cell Membrane

Summary: How does a cell just sprout out of a preexisting cell. Like what the. That makes no sense yet it really does and here is why. There are two major parts of creating a new cell from a pre existing one. First of all you need to use mitosis. Mistis is not a very simple task though. It requires 4 stages as seen up above.  I don't want to have to get into crazy details because well a reader gets bored so lets make this quick. First of all you have two daughters( the black dots of pulling points in the cells) that are what mostly drives the two cells apart. First of all they strand some spindles to the connections in the middle ( nucleus) Then the two daughter start to pull apart from each other. Then they copy the Dna. Ok I know DNA what even is that. Well it is like the architecture of a building, the blueprints of all that is to be done. DNA is your blue prints. Ok since they have the DNA then your cells can split. Now we have that cytosis well this is how the cell opens itself up and collect molecules which makes it so it can start all over. Then they all live happily ever after.  Alright lets move on.

S&EP: This week we have some of the most Analise of data than ever before. This week we have been using Gizmos and the papers that come with it to fully digest the ideas of cell division, We have gotten to see through visually how this process works and have also drafted down the information. We have been even asked lots of scientific question on how this works and the steps it takes. With these new sheets I have really learned a lot more.


XXC: This week we have used Cause and Effect. You remember way back when you look at title. Well it talks about The Cell's Membrane. This is it's time to shine. We have discovered lots about the importance of the cell membrane and soon enough you will know to. The cell membrane  is a thin wall between the outside world and the cells in your body. it is not just a bag for the cell it is also the way that the  molecules get in and out of the cell. We have learned about his using the simple example of an egg. An egg has a cell membrane and we can use test to deserve what it can really do. The cell membrane can take in usually liquids so that is what we testred. We say that effects the solvents did to the cell/egg. we saw 3 things happen with the different types of liquid . I fell they were a perfect example of how cause and effect happens in our body every day.
