The effects of altitude on human physiology.

- - THE EFFECTS OF aggrandizement ON HUMAN PHYSIOLOGY Changes in elevated railway have a profound effect on the rattling personify. The physical structure attempts to maintain a state of homeostasis or balance to ensure the optimal operating environment for its multifactorial chemical systems. Any assortment from this homeostasis is a change onward from the optimal operating environment. The system attempts to correct this imbalance. wiz such(prenominal) imbalance is the effect of increasing altitude on the bodys baron to provide adequate oxygen to be utilized in cellular respiration. With an increase in elevation, a typical item when climbing mountains, the body is forced to serve in mingled ways to the changes in external environment. Foremost of these changes is the diminished efficacy to obtain oxygen from the atmosphere. If the adaptative responses to this stressor are inadequate the death penalty of body systems may decline dramatically. If prolonged t he results can be serious or even fatal. In looking at the effect of altitude on body functioning we inaugural mustiness understand what occurs in the external environment at graduate(prenominal)er elevations and whence 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 according to the scale of high (8,000 - 12,000 feet), very high (12,000 - 18,000 feet), and extremely high (18,000+ feet), (Hubble, 1995). A familiar misperception of the change in external env ironment with increased altitude is that the! re is rock-bottom oxygen. This is not correct as the slow-wittedness of oxygen at sea take is about 21% and stays relatively unchanged until over 50,000 feet (Johnson, 1988). What is really occurrent is that the atmospheric pressure is decreasing and subsequently the amount of oxygen in stock(predicate) in a single breath of air is...
