Document Summary
Complement system: the complement system, like antibodies, is a series of proteins. There are millions of different antibodies in your blood stream, each sensitive to a specific antigen. There are only a handful of proteins in the complement system, and they are floating freely in your blood. The complement proteins are activated by and work with (complement) the antibodies, hence the name. They cause lysing (bursting) of cells and signal to phagocytes that a cell needs to be removed. T cells and b cells in the white blood cells recognize certain things. The t cells have receptors and one arm where antibodies (b cells) have two arms. Mature t cells and b cells have only one shape. Mhc i: grab proteins inside cell and display proteins on the outside so the immune system can see it. Hae to balance gearing down the immune system and getting sick.
