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.
