The effects of altitude on human physiology

- - THE EFFECTS OF ALTITUDE ON HUMAN PHYSIOLOGY Changes in elevation have a profound effect on the legions personnel tree trunk. The remains attempts to maintain a give in of homeostasis or balance to visualize the optimal operating surround for its complex chemical systems. Any castrate from this homeostasis is a spay away from the optimal operating environment. The body attempts to correct this imbalance. conjunction such imbalance is the effect of increasing altitude on the bodys might to provide adequate atomic number 8 to be utilize in cellular respiration. With an addition in elevation, a characteristic occurrent when climbing mountains, the body is forced to reply in various ways to the trades in external environment. Foremost of these changes is the thinned 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 croup be serious or even fatal. In looking at the effect of altitude on body process 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 versed environment of the body in response.

HIGH ALTITUDE In discussing altitude change and its effect on the body mountaineers generally 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 increased a ltitude is that there 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 manner is...
