| Description: Types of cells involved in the inflammatory response. (1) Platelets release blood-clotting proteins at the wound site. (2) Mast cells secrete factors that mediate dilation and constriction of blood vessels. (3) Neutrophils secrete factors that kill or degrade pathogens. Neutrophils and macrophages secrete factors that remove pathogens by phagocytosis. (4) Macrophages secrete cytokines that attract immune system cells. Blood platelets release proteins at the wound site. Mast cells secrete factors that go into the blood vessel. Neutrophils come out of the blood vessel and engulf pathogens. Macrophages secrete cytokines, which signal the path to the injury cite, which initiate tissue repair.
