Detailed explanation-1: -Complement also possesses anti-inflammatory functions: it binds to immune complexes and apoptotic cells, and assists in their removal from the circulation and damaged tissues [2, 3]. The complement proteins are activated by, and work with IgG and IgM antibodies, hence the name ‘complement’.
Detailed explanation-2: -The complement system is part of your body’s immune system that cleans up damaged cells, helps your body heal after an injury or an infection and destroys microscopic organisms like bacteria that make you sick. Your complement system is the front line of defense for your immune system.
Detailed explanation-3: -The most important action of complement is to facilitate the uptake and destruction of pathogens by phagocytic cells. This occurs by the specific recognition of bound complement components by complement receptors (CRs) on phagocytes.
