Document Summary

Single cell -> multiple omnipotent cells -> highly specialized organ systems. Cells with common function fuse to form organs. We require a feedback system to coordinate the responses of different organs. Example: eyes (receptor) -> brain (integrator) -> muscles (effector) Homeostasis: chemical level: molecule in the membrane that encloses a cell, cellular level: cell in stomach lining, tissue level: layers of tissue in stomach wall, organ level: stomach, body system level: digestive system, organism level: whole body. Water input: from outside environment and inside us. Maintenance: use it, store it, incorporate into other molecules. Output: consumed in body, excrete it (sweat, lungs, kidneys, tears) Things that alter our set points are compensated for by our physiological systems (feedback regulation) Most common occurs at whole body, organ, tissue, and cell levels. E. g. when you heat up you sweat to cool off. E. g. when you cut yourself, your body increases production of clot factors.
