Document Summary
Innate vs. acquired immunity: non-specific barriers, eyes, nose, digestive tract, ears, respiratory tract, non specific white blood cells, mast cell, neutrophil, macrophage/ monocyte. Fundamental characteristics of immune system: responds adaptively to foreign invaders. It displays long term memory that is both quantitatively and qualitatively different from the primary response: can distinguish self from non self. Immune system is the only system in the body that has all four of these. Active immunity: comes from a response to an infectious disease. Passive immunity: transferred from one individual to another via antibodies, b cells create antibodies. 10/17: changing rift valley geology and human evolution. Plio-pleistocene: pliocene pleistocene boundary, pleistocene begins with permanent ice caps on the earth"s poles (2. 5 million, generally around 4-1. 5 million years ago years ago) Changes in east african climate and habitat: adaptive strategies for habitat change from jungle to savannah.
