What is the main function of complement?

The main function of the complement system is to enhance the ability of antibodies and phagocytic cells to clear pathogens from an organism. It consists of a series of proteins that work together to opsonize pathogens, promote inflammation, and directly lyse microbial cells. By marking pathogens for destruction and facilitating their removal, the complement system plays a crucial role in the immune response. Additionally, it helps regulate various immune processes to maintain homeostasis.
