inflammation
The main function of complement proteins is to aid in the destruction of pathogens by piercing their outer membranes (cell lysis) or by making them more attractive to phagocytic cells such as macrophages (a process known as opsonization). Some complement components also promote inflammation by stimulating cells to release histamine and by attracting phagocytic cells to the site of infection.
An inflammatory response resulting from injury is classified as acute inflammation when it lasts only a few days.12
During this period, the body works to localize and eliminate the injurious agent and remove damaged tissue to facilitate healing. While the initial vascular changes, such as vasodilation, may last from 15 minutes to several hours, the overall process of clearing cellular debris by white blood cells typically concludes within this short timeframe. If the inflammatory response persists beyond this duration, it may be categorized as chronic inflammation.123
