My project is on the immune system. Something I already knew about the immune system is that the immune system helps prevent diseases. I will list the major organs in the immune system. The immune system helps your body by using white blood cells.
The function of the immune system is to keep your body healthy. Leukocytes are part of the defense system that kill germs and disease. There are many types of white blood cells. There are the phagocytes and the lymphocytes. Phagocytes chew up invading germs. Lymphocytes help the body remember germs. Leukocytes are found in the spleen and in bone marrow.
Disease fighting blood cells start in the bone marrow. Each work on different types of diseases. Netrophils move around your blood to search for foreign cells. Macrophages clean wounds and other white blood cells that have been damaged. Lymphocytes attack bacterial and fungal infections.
There are two types of lymphocytes. B Cells produce antibodies to mark bad cells to be destroyed. T Cells seach for hidden germs and diseases. They use antibodies to mark germs and diseases so other cells know to destroy them. Your cells are marked with Human Leukocyte Antigen.
The lymphatic system is a bunch of small nodes that filter out bad germs that could harm your body. Lymph nodes are located in your throat, arm pits, knees and groin area. When you get sick your immune system helps you get better. You know if your immune system is working if you were sick then you eventually got better. If you get cut and it doesn’t get infected, your immune system is working. When you are sick, your lymph nodes swell.
If your immune system is not working properly you may get sick. Sometimes your immune system will attack important parts of your body. This is called auto immune disease. My mom has sjogrens syndrome. This is when your body attacks its own moisture producing glands. Moisture glands are in your eyes and mouth sometimes it also effects organs such as kidneys liver and lungs.
I learned that without your immune system you would get sick all the time. Your immune system helps you by killing diseases. It uses your kidneys and your liver and white blood cells. It also uses lymph nodes to prevent germs and sickness and diseases. So without your immune system you would be sick almost every day.
