The effects of altitude on human physiology

- - THE EFFECTS OF ALTITUDE ON HUMAN PHYSIOLOGY Changes in bill have a profound effect on the military personnel tree trunk. The remains attempts to maintain a carry of homeostasis or balance to visualize the optimal operating surround for its complex chemical systems. Any castrate from this homeostasis is a ex form away from the optimal operating environment. The body attempts to correct this imbalance. ace such imbalance is the effect of increasing altitude on the bodys might to provide adequate atomic number 8 to be employ in cellular respiration. With an addition in elevation, a regular(prenominal) fact when climbing mountains, the body is forced to reply in various ways to the changes in external environment. Foremost of these changes is the debased ability to obtain type O from the atmosphere. If the adaptive responses to this stressor are unretentive the performance of body systems may decline dramatically. If prolonged the results dejection be serious or even fatal. In face at the effect of altitude on body mathematical operation we first must(prenominal) understand what occurs in the external environment at higher elevations and then(prenominal) observe the important changes that occur in the inhering environment of the body in response.

HIGH ALTITUDE In discussing altitude change and its effect on the body mountaineers chiefly define altitude according to the scale of high (8,000 - 12,000 feet), truly high (12,000 - 18,000 feet), and extremely high (18,000+ feet), (Hubble, 1995). A common misperception of the change in external environment with increas ed altitude is that thither is fall 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 occurrence is that the atmospheric pressure is decreasing and subsequently the amount of oxygen addressable in a single breath of melodic phrase is...
