Document Summary
Runners vs body builders: runners have red muscle due to increase in mitochondria slow twitch, body builders have white muscle fast twitch, plastic tissue (skeletal muscle, aging, microgravity, denervation, starving can lead to atrophy of muscles. Integration / coordination of physiological systems: ex. Physiology (looking at forest) vs pathophysiology (looking at individual trees and their differences) Homeostasis: most physiological variables such as blood pressure, body temperature, and blood gases, are maintained within predictable range, ex. Room temp decreases increase in heat loss decrease in body temp . Control systems refer to pathophysiology: feedback loops or systems are common mechanism to control physiological processes, positive feedback ~ enhances production of product or accelerates process, negative feedback ~ brings about responses that move variable opposite to. Adaptation and acclimatization direction of its original change: adaptation ~ characteristic that favors survival in specific environments, acclimatization ~ improved functioning of already existing homeostatic system; sometimes this is due to prolonged exposure to environmental change.
