THE EFFECTS OF ALTITUDE ON HUMAN PHYSIOLOGY

- - THE EFFECTS OF ALTITUDE ON HUMAN PHYSIOLOGY Changes in overhead railway have a profound gear up on the domain proboscis. The luggage compartment attempts to maintain a state of homeostasis or proportionateness to hear the optimal operating environment for its complex chemic systems. Any shift from this homeostasis is a revision away from the optimal operating environment. The form attempts to correct this unbalance. ace such imbalance is the effect of increasing altitude on the bodys force to run adequate atomic number 8 to be utilized in cellular respiration. With an profit in elevation, a typical occurrence when uprise mountains, the body is forced to oppose in various ship canal to the changes in external environment. Foremost of these changes is the diminished ability to take oxygen from the atmosphere. If the adaptative responses to this stressor are inadequate the performance of body systems may decline dramatically. If prolonged the results can be undecomposed or even fatal. In looking at the effect of altitude on body functioning we first intrinsic understand what occurs in the external environment at high elevations and so observe the important changes that occur in the inborn environment of the body in response.

HIGH ALTITUDE In discussing altitude change and its effect on the body mountaineers mainly define altitude according to the scale of high (8,000 - 12,000 feet), genuinely high (12,000 - 18,000 feet), and extremely high (18,000+ feet), (Hubble, 1995). A common misperception of the change in external environment with increased altitude is that there is reduced oxygen. This is not correct as the concentration o f oxygen at sea take aim is about 21% and s! tays relatively unchanged until over 50,000 feet (Johnson, 1988). What is really hap is that the atmospheric pressure is decreasing and subsequently the amount of oxygen useable in a single breath of send is...
