Humoral immunity refers to destruction of antigens by antibodies. Immunity can be inborn or acquired. Both naturally and artificially acquired immunity can be actively or passively acquired. Cell-mediated immunity refers to destruction of antigens by T cells. Exposure to disease-causing organisms over one's lifetime stimulates the process of acquired immunity. Humoral or antibody-mediated immunity protects the body against circulating disease-producing antigens and bacteria.
