the body's defense system that protects against foreign invaders (e.g., microorganisms) and cancerous cells. Some immune defenses are nonspecific (e.g., phagocytosis). Defenses against specific antigens are of 2 types: cell-mediated (TH1) and humoral (antibody-based, or TH2). Organs of the immune system include the lymph nodes, spleen, thymus, tonsils and bone marrow.
