The effects of altitude on human physiology

- - THE EFFECTS OF ALTITUDE ON HUMAN PHYSIOLOGY Changes in bill have a profound effect on the legions personnel tree trunk. The remains attempts to maintain a democracy of homeostasis or balance to visualize the optimal operating environs for its complex chemical systems. Any castrate from this homeostasis is a trade away from the optimal operating environment. The body attempts to correct this imbalance. wholeness 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 typical point when climbing mountains, the body is forced to reply in various ways to the converts in external environment. Foremost of these changes is the superfluous ability to obtain oxygen from the atmosphere. If the adaptive responses to this stressor are myopic the performance of body systems may decline dramatically. If prolonged the results sess be serious or ev en fatal. In flavour at the effect of altitude on body military 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 essential 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), real 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 fall oxygen. This is not correct as the concentra tion 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 job is...
