__**Function**__ The [|Immune System] comes into action when a virus or other sickness enters the body. A B cell will find the virus and label it with an antibody. An antibody is a protein that connects to the virus’ antigen and helps destroy the virus. A phagocyte will recognize the antibody destroy the virus. The body will keep some of the virus so it will no what to do if the virus comes back. For no the virus is exterminated. __Organs__ The Immune System has less known organs than the other system. An example is the thymus gland located in the thorax. The [|thymus gland] produces T cells. Another organ in the Immune System is [|Bone] [|Marrow], which is inside all bones. The Bone Marrow produces blood cells, in a process called hematopoises, which help fight diseases. There are also the [|Lymph Nodes] located in the neck, armpits, groin and behind the knees. The Lymph Nodes contain Immune cells and help filter out viruses. A little more known organ is the [|spleen], which is in the upper left side of the abdomen. The spleen filters antigens out of the body. All these organs work together to fight sicknesses.

__**Other Systems the**__ __**Immune System Works with**__

The Immune System has to work with the other systems of the body. The Immune System is normally not involved with the Reproductive System but they have a disease in common, [|HIV/AIDS]. HIV/AIDS is usually passed by sexual contact, and once it’s in the body it shuts down the Immune System and reverses it. The Immune System also works with the Respiratory System when coughing and sneezing spreads germs. The Digestive System is about eating and when you eat healthy foods you’ll have a healthy Immune System. The Endocrine System and Immune System share the Thymus Gland as an organ of the system. The Immune system works with some systems but not all.

__Health__

The Immune System is important to keep healthy because it fights what gets you sick. In order to keep the Immune System healthy you must wash your hands to get rid of germs. You must also eat healthy foods. You should exercise too. The most important way to keep the Immune System healthy is to have regular checkups so the doctor can tell you if you have an illness. If you don’t keep the Immune System healthy it could affect your whole body.
