THE EFFECTS OF ALTITUDE ON HUMAN PHYSIOLOGY

- - THE EFFECTS OF ALTITUDE ON HUMAN PHYSIOLOGY Changes in top have a profound ensnare on the humankind proboscis. The luggage compartment attempts to maintain a state of homeostasis or agreement to hear the optimum operating environment for its complex chemical systems. Any shift from this homeostasis is a flip away from the optimal operating environment. The luggage compartment attempts to correct this instability. ace such imbalance is the effect of increasing altitude on the bodys force to depict adequate atomic number 8 to be utilized in cellular respiration. With an profit in elevation, a typical occurrence when lift 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 bugger off 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 unsafe or even fatal. In looking at the effect of altitude on body functioning we first demand understand what occurs in the external environment at high elevations and so observe the important changes that occur in the upcountry environment of the body in response.

HIGH ALTITUDE In discussing altitude change and its effect on the body mountaineers loosely 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 common misperception of the change in external environment with increased altitude is that in that respect is reduced oxygen. This is not correct as the concentration of oxygen at sea take aim is about 21% and! stays relatively unchanged until over 50,000 feet (Johnson, 1988). What is really accident is that the atmospheric pressure is decreasing and subsequently the amount of oxygen useable in a single breath of channelize is...
