(cid:1006)(cid:1012)(cid:1010)-(cid:1006)(cid:1013)(cid:1007) Innate immunity: exists in a person without prior contact with an antigen, nonspecific response, neutrophils and monocytes are wbcs primarily involved. The benefit of this immunity is its immediate effect: unfortunately, passive immunity is short-lived because the host does not synthesize the antibodies and consequently does not retain memory cells for the antigen. Antigen: an antigen is a substance that elicits an immune response, most antigens are composed of proteins. If removed in childhood predisposition to life-threatening septicemia: lymphocytes are produced in the bone marrow and eventually migrate to the peripheral organs. Mononuclear phagocytes: system incl. monocytes in the blood and macrophages found throughout the body, critical role in the immune system, capturing (through phagocytosis), processing, and presenting the antigen to the lymphocytes, stimulates a humoral or cell-mediated immune response.
