Document Summary

Single cell > multiple omnipotent cells > organ systems. If there is a mistake in first cell, will continue into next cells. @ 128 cells = omnipotent (stem) cells (any kind of cells) Cells with common function fuse to form organs. Communication between organs chemically: feedback system, sensory system, relay system, response system. Negative feedback to shut off system responsible for the response (homeostasis) Homeostasis can occur at: chemical, cellular, tissue, organ, body system, organism levels. Gains should equal losses, if not we get diseases. Most of system exist at set points (ex. body temp: things that alter these are compensated for by our physiological systems. Feedback types: negative feedback, response counteracts the initial stimulus, most common, ex. When your body gets warm you cool off: positive feedback, response adds to initial stimulus, less common, ex. clot formation, ex. childbirth. 2: ex. oxygen binding to hemoglobin, feedforward regulation, prime system for challenges to come, anticipatory situations, smell food salivate.
