(the weapons).Antibody are shaped proteins they will attack anything that is bad for your body and that might cause you any health problems, They are unique. There's also a T helper cell and they are white blood cells that contact activate B cells and killer T cells. Well Killer T cells are the ones that attack good cells that have been infected. The difference between a T cell and a B cell is that the T cells are white blood cells that contact activate B cells and killer T cells , and the B cells search for weapons. The difference between a T cell and a Killer T cell is that the T cell contact and the killer T cells attack.
The macrophage is the big eater. micro is big and phage is eater. They eat anything marked with an antibody. The difference between a bacteria and a virus is that the bacteria can multiply and the virus needs hosts in order to reproduce.
