The principal biological role of the complement system, found in all vertebrate blood, appears to be as an effector mechanism in the immune defence against infection by microorganisms. It is a complete mechanism in which activation products of the complement components cause lysis of cellular antigens, attract phagocytic cells to the site of activation, and facilitate uptake and destruction by the phagocytes.
