Document Summary

Immunity: bod(cid:455)(cid:859)s a(cid:271)ilit(cid:455) to fight off har(cid:373)ful (cid:373)i(cid:272)ro-organisms (pathogens) that invade it, recognition of self vs. non-self. Factors of emergence: human demographics/behavior, technology/industry, economic development and land use. International travel and commerce: microbial adaptation and change, decline of public health. Lymphatic system: network of tissues/organs that help rid body of toxins/waste/unwanted materials, transports lymph (milky body fluid containing lymphocytes). Antigens: any foreign substance that elicits immune response when introduced to tissues of susceptible animals; capable of combining with specific antibodies formed, have specific sites that bind to antibodies. Immunity and immune response: (two cellular systems: humoral/circulating antibody system, b cells, cell mediated immunity, t cells.
