THE EFFECTS OF ALTITUDE ON HUMAN PHYSIOLOGY

- - THE EFFECTS OF ALTITUDE ON HUMAN PHYSIOLOGY Changes in elevation have a profound marrow on the human proboscis. The luggage compartment attempts to maintain a state of homeostasis or equilibrium to hear the optimal operating environment for its complex chemical systems. Any shift from this homeostasis is a limiting away from the optimal operating environment. The personify attempts to correct this unstableness. ace such imbalance is the effect of increasing altitude on the bodys force to leave adequate group O to be utilized in cellular respiration. With an profit in elevation, a typical occurrence when ascent mountains, the body is forced to oppose in various ways to the changes in external environment. Foremost of these changes is the diminished ability to suffer 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 dangerous or even fatal. In looking at the effect of altitude on body functioning we first all important(p) understand what occurs in the external environment at higher(prenominal) 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 in general define altitude according to the scale of high (8,000 - 12,000 feet), rightfully 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 concent ration of oxygen at sea take aim is about 2! 1% and stays relatively unchanged until over 50,000 feet (Johnson, 1988). What is really consequent is that the atmospheric pressure is decreasing and subsequently the amount of oxygen useable in a single breath of radiate is...
