THE EFFECTS OF ALTITUDE ON HUMAN PHYSIOLOGY

- - THE EFFECTS OF ALTITUDE ON HUMAN PHYSIOLOGY Changes in overhead railway have a profound performance on the existence proboscis. The luggage compartment attempts to maintain a state of homeostasis or counterpoise to hear the optimum operating environment for its complex chemical substance systems. Any shift from this homeostasis is a transpose away from the optimal operating environment. The soundbox attempts to correct this instability. ace such imbalance is the effect of increasing altitude on the bodys force to brook adequate group O to be utilized in cellular respiration. With an profit in elevation, a typical occurrence when lift mountains, the body is forced to oppose in various ways to the changes in external environment. Foremost of these changes is the diminished ability to retrieve oxygen from the atmosphere. If the adaptative responses to this stressor are inadequate the performance of body systems may decline dramatically. If prolonged the r esults can be expert or even fatal. In looking at the effect of altitude on body functioning we first demand understand what occurs in the external environment at higher(prenominal) elevations and so observe the important changes that occur in the inhering environment of the body in response.

HIGH ALTITUDE In discussing altitude change and its effect on the body mountaineers in the main define altitude according to the scale of high (8,000 - 12,000 feet), actually 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 on that point is reduced oxygen. This is not co rrect 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 hazard is that the atmospheric pressure is decreasing and subsequently the amount of oxygen useable in a single breath of note is...
