If germs get through the body’s physical and chemical barriers into he bloodstream, a mixture of liquid proteins called complement is activated and attacks them. The complement system includes a series of proteins. While 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. They float freely in your blood. Complements are manufactured in the liver. The complement proteins are activated by and work with (complement) the antibodies. They cause lysing (bursting) of cells and signal to phagocytes that a cell needs to be removed.
