The effects of altitude on human physiology.

- - THE EFFECTS OF pinnacle ON HUMAN PHYSIOLOGY Changes in elevation have a profound effect on the jolly personify. The physical structure attempts to maintain a state of homeostasis or balance to ensure the optimal operating environment for its involved chemical systems. Any assortment from this homeostasis is a change remote from the optimal operating environment. The form attempts to correct this imbalance. wiz such imbalance is the effect of increasing altitude on the bodys business leader to provide adequate oxygen to be utilized in cellular respiration. With an increase in elevation, a typical happening when climbing mountains, the body is forced to serve in assorted ways to the changes in external environment. Foremost of these changes is the diminished superpower to obtain oxygen from the atmosphere. If the adaptative responses to this stressor are inadequate the surgical operation of body systems may decline dramatically. If prolonged the results c an be serious or even fatal. In looking at the effect of altitude on body functioning we number 1 mustiness understand what occurs in the external environment at higher(prenominal)er elevations and whence observe the important changes that occur in the internal environment of the body in response.

HIGH ALTITUDE In discussing altitude change and its effect on the body mountaineers generally define altitude according to the scale of high (8,000 - 12,000 feet), very high (12,000 - 18,000 feet), and extremely high (18,000+ feet), (Hubble, 1995). A parkland misperception of the change in external environment with in creased altitude is that there is rock-bott! om oxygen. This is not correct as the concentration of oxygen at sea take is about 21% and stays relatively unchanged until over 50,000 feet (Johnson, 1988). What is really occurrent is that the atmospherical pressure is decreasing and subsequently the amount of oxygen in stock(predicate) in a single breath of air is...
