Need help drawing meaningful cartoons for biology! In this project, you will present a drawn story describing an encounter between an "invader" from outside our body and the body's defense response. It must include at least five story blocks: initial contact (first line of defense), inflammatory response (second line of defense), specific defenses (2 blocks), and persistent (memory) effects. if you could, can you include cells and chemicals important to the immune system as well as organs that the cells are stored and released from, among other additional information.

Lymphocytes are made in the bone marrow. As well as B cells and T cells. B cells are in the blood and just float around until it comes across an antigen that it does not recognize. An antigen is a specific protein that is around a cell these antigens are different from the ones in your own body so when a B cell finds an antigen that it does not recognize it produces antibodies. These antibodies bind to the foreign cell (bacteria) and when they do the foreign cells start clumping together and alert T cells. And when T cells, also floating in the blood, bind to a foreign antigen they make cytokines. Cytokines alert the body of an invader. Once alerted the body sends out phagocytes. Phagocytes are pretty much white blood cells. These phagocytes then engulf the big clump of foreign cells that the antigens made. And the enzymes that are all around the phagocyte break down the invading cell. Then lets say for example the same foreign cell attacks your body again at a different time, Memory T cells (Produced by the body the first time the foreign cell entered the body) "remember" that cell because of the antigen. (No T cells and B cells are the same.... there are only a few copies of each in the body at one time... This is why it takes so much time to get better from things like the cold or chicken pox. Because EVERY T cell has to try and bind to the antigen on the foreign cell) Since T cells are the cells that alert the phagocytes it is important to have as many as possible. The Memory T cell just binds to the same antigen as the as the original T cell did. This means that when you get sick lets say from chicken pox... You will get better faster, or not even be sick at all because the first time you had it Memory Tcells were made. So that if the same pathogen (same thing as a foreign cell) entered the body again it could be destroyed much faster. Memory T cells also just float around in the blood.
