How do humans adapt to life at high altitudes
The human body can adapt to high altitude through both immediate and long-term acclimatization. At high altitude, in the short term, the lack of oxygen is sensed by the carotid bodies, which causes an increase in the breathing depth and rate (hyperpnea). However, hyperpnea also causes the adverse effect of respiratory alkalosis, inhibiting the respiratory center from enhancing the respiratory rate as much as would be required. Inability to increase the breat… WebFeb 1, 2006 · Adaptations to life at high elevation Gradients in altitude represent natural experiments by providing substantial changes in numerous environmental parameters. …
