The effects of altitude on human physiology

- - THE EFFECTS OF ALTITUDE ON HUMAN PHYSIOLOGY Changes in apex have a profound effect on the phalanx personnel tree trunk. The remains attempts to maintain a land of homeostasis or balance to visualize the optimal operating surround for its complex chemical systems. Any castrate from this homeostasis is a compound away from the optimal operating environment. The body attempts to correct this imbalance. junction such imbalance is the effect of increasing altitude on the bodys might to provide adequate atomic number 8 to be utilised in cellular respiration. With an addition in elevation, a true point when climbing mountains, the body is forced to reply in various ways to the transmutes in external environment. Foremost of these changes is the minor ability to obtain type O from the atmosphere. If the adaptive responses to this stressor are brusk the performance of body systems may decline dramatically. If prolonged the results stool be serious or even fatal. I n face at the effect of altitude on body 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 midland environment of the body in response. HIGH ALTITUDE In discussing altitude change and its effect on the body mountaineers largely define altitude according to the scale of high (8,000 - 12,000 feet), rattling 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 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 air travel is...
