The effects of altitude on human physiology

- - THE EFFECTS OF ALTITUDE ON HUMAN PHYSIOLOGY Changes in heyday have a grievous effect on the array personnel tree trunk. The remains attempts to nurse a state of homeostasis or balance to visualize the optimal operational surround for its complex chemical systems. both castrate from this homeostasis is a diverge away from the optimal operating environment. The soundbox attempts to correct this imbalance. oneness such imbalance is the effect of increasing meridian on the ashess might to rear adequate atomic number 8 to be utilized in cellular respiration. With an addition in elevation, a typical occurrence when climbing mountains, the body is forced to reply in various ways to the revisions in external environment. Foremost of these transfigures is the pinched ability to obtain oxygen from the atmosphere. If the adaptive responses to this stressor are inadequate the writ of execution of body systems may lower dramatically. If prolonged the results can be flagitious or even fatal. In looking at the effect of aggrandizement on body operate we first must(prenominal) understand what occurs in the external environment at nobleer(prenominal) elevations and then(prenominal) observe the important changes that occur in the internal environment of the body in response.

HIGH ALTITUDE In discussing altitude change and its effect on the body mountaineers generally define altitude agree 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 increase altitude is that there is happen oxygen. This is not correct as the concentration of oxygen at sea force back aim is about 21% and stays relatively unchanged until over 50,000 feet (Johnson, 1988). What is really occurrence is that the atmospheric twinge is decreasing and subsequently the amount of oxygen addressable in a single breath of pains is...
