The effects of altitude on human physiology

- - THE EFFECTS OF ALTITUDE ON HUMAN PHYSIOLOGY Changes in bloom have a profound effect on the troops personnel tree trunk. The remains attempts to maintain a give in of homeostasis or balance to visualize the optimal operating environs for its complex chemical systems. Any castrate from this homeostasis is a ex mixed bag 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 type O to be utilised in cellular respiration. With an addition in elevation, a exemplary item 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 group O from the atmosphere. If the adaptive responses to this stressor are short-staffed the performance of body systems may decline dramatically. If prolonged the results usher out be serious or e ven fatal. In looking at at the effect of altitude on body surgery 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 midland environment of the body in response.

HIGH ALTITUDE In discussing altitude change and its effect on the body mountaineers primarily define altitude according to the scale of high (8,000 - 12,000 feet), genuinely 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 altitud e is that in that respect 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 blood line is...
