Phagocytes remove most of the complexes, but some lodge in the walls of blood vessels There the complexes activate complement Antigens combine with antibodies to form antigen- antibody complexes Antigen Inactive complement Antibody Antigen-antibody complex Active complement

Phagocytes remove most of the complexes, but some lodge in the walls of blood vessels There the complexes activate complement Antigen-antibody complexes and activated complement attract and activate neutrophils which release inflammatory chemicals Antigens combine with antibodies to form antigen- antibody complexes Antigen Inactive complement Neutrophil Antibody Antigen-antibody complex Active complement Inflammatory chemicals
