dio Biol 4000: Comparative Animal Physiology Assignment 2| Two routes to usable adaptation: Tibetan and Andean high- aggrandizement natives review | Devin McManus| | Acclimatization occurs as a short-term adjustment during transition into different situations. In the oddball of this paper it is the transition from low altitude (higher PO2 levels) to high altitude (lower PO2 levels). Lowlanders have specific physiologic adaptations of living in areas with a relatively high concentration of oxygen (as oppose to those in higher altitudes). These adaptations at high altitudes have little to no affect and in some cases keystonefire. Lowlanders basal metabolic order (BMR) increases from 17% to 27% initially and gradually returns to jolly higher than normal levels, this can take up to ane year. On that same note the maximum metabolic rate (MMR) makes 20% to 30% during the first few weeks and gradually increases back to close to normal levels as if at sea-level. Also, when transitioning to a high-altitude environment lowlanders exhibit a hypoxic ventilatory response (HVR) which includes hyperventilation, which is expected, as PO2 levels start to decrease respiration increases in order to dream more oxygen.

As lowlanders begin to adapt to the high-altitude environments more physiological changes start to show. From biopsies of leg muscle we know that mitochondrial concentrations decline, this also contributes to the drop in BMR (due to proton leak) and a decrease in aerophilous cleverness. HVR also begins to decline, with an overshoot (less aerobic activity = lower levels of push = lower levels of oxygen needed = lower respiration). Capillary capacity increases to supply tissues more efficiently, and NO (nitric acid, a vasoconstrictor) is downregulated. This downregulation is an effect of adaptations at sea-level. This causes constriction, which intern leads to pulmonary hypertension (hence, the backfire stated earlier). other important factor (not...
