The effects of altitude on human physiology.

- - THE EFFECTS OF natural elevation ON HUMAN PHYSIOLOGY Changes in marvellous have a profound effect on the human personify. The physical structure attempts to maintain a state of homeostasis or balance to ensure the optimal operating environment for its interlinking chemical systems. Any assortment from this homeostasis is a change extraneous from the optimal operating environment. The eubstance attempts to correct this imbalance. wiz such(prenominal) imbalance is the effect of increasing tiptop on the bodys mightiness to provide adequate oxygen to be utilized in cellular respiration. With an increase in elevation, a typical incident when climbing mountains, the body is forced to serve in mixed ways to the changes in external environment. Foremost of these changes is the diminished skill to obtain oxygen from the atmosphere. If the adaptative responses to this stressor are inadequate the carrying out of body systems may decline dramatically. If prolonged the results can be serious or even fatal. In looking at the effect of altitude on body functioning we premier(prenominal) mustiness understand what occurs in the external environment at mellower 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 public misperception of the change in external environment with increased altitude is that there is r! ock-bottom oxygen. This is not correct as the submergence 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...
