The immune system is the bodys system of defense against infectious diease. It protects the body from foreign substances and pathogenic organisms. The immune system includes the thymus, bone marrow, and lymphoid tissues. The immune system actually fights unfamiliar germs, bacteria, viruses, and parasites. In certain cases your immune system can turn against your body’s own cells. The immune system can recognize invading germs because they will have different antigens than your body. The immune system can guard you from viruses such as colds, flues, tonsillitis, and ear infections. The immune system protects us from several different things and is something needed for each person for survival without the immune system we wouldn’t have anything to fight for us and our bodies would eventually be overrun by germs, diseases, and or viruses. Continuing on I will explain why the proper function of the immune system is so important to all other systems in our body.

In the body there are two main fluid systems. They are the “blood and the lymph systems and these two systems are responsible for transporting the agents of the immune system” (uhaweb, 2001, para. 6). The transporting of these are important to making sure we can continue to fight off antigens that are not suppose to be in our body. I watned to include this picture as it is a breakdown of all the major cells in the blood system and because the blood system is part of the transport system I found this to be important for us to know what is all included in the blood system. The immune system fights all the bad and kills it. Once the immune system fights something it in turn builds up anitbodies against that making it harder for that specific thing to attatck you and make you ill again.

The immune system works with the lymph system. The lymphoid system has primary organs and secondary. The primary organ is bone marrow and...
