The effects of altitude on human physiology

- - THE EFFECTS OF ALTITUDE ON HUMAN PHYSIOLOGY Changes in vertex have a profound effect on the array personnel tree trunk. The remains attempts to maintain a put in of homeostasis or balance to visualize the optimal operating surround for its complex chemical systems. Any castrate from this homeostasis is a qualifying away from the optimal operating environment. The body attempts to correct this imbalance. single such imbalance is the effect of increasing altitude on the bodys might to provide adequate group O to be employ in cellular respiration. With an addition in elevation, a regular occurrence when climbing mountains, the body is forced to reply in various ways to the flip-flops in external environment. Foremost of these changes is the diminished ability to obtain atomic number 8 from the atmosphere. If the adaptive responses to this stressor are s contributet(p) the performance of body systems may decline dramatically. If prolonged the results can be s erious or even fatal. In looking at the effect of altitude on body functioning 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 sexual 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), unfeignedly high (12,000 - 18,000 feet), and extremely high (18,000+ feet), (Hubble, 1995). A common misperception of the change in external environment with increa sed 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 agate line is...
