Adaptation to Altitude, high activity, and other physical stressors
Acute Mountain Sickness
A common ailment upon first arriving at high altitude characterized by headache, dizziness, lightheadedness, and nausea due to lowered oxygen intake or respiratory alkalosis.
The production of energy by metabolism in the presence of oxygen
The highest rate at which oxygen can be consumed in metabolism
The aerobic capacity per body weight
The tiny air sacs in the lungs across the surface of which the oxygen and carbon dioxide are exchanged with blood
The pressure of the atmosphere as measured by a barometer
The accumulation of fluid in brain tissue
The accumulation of fluid in brain tissues
Chronic Mountain Sickness
A condition of natives or long-term residents of high altitude characterized by a loss of acclimatization, lowered ventilation rate, and a great increase in polycythemia.
An abnormal accumulation of fluid resulting in swelling
The protein that gives redblodded cells their color and their capacity to transport oxygen and carbon dioxide
Low oxygen levels
The amount of force a muscle can provide based ont he cross sectional area of muscle
Naturally occurring perils such as storms, earthquakes, tsunamis, and volcanic eruptions
Optimal foraging Strategies
Foraging techniques that are most effective or efficient
The ability to maintain homeostatic conditions during strenuous activity or to rapidly restore those conditions after exercise
A condition in which the percent of blood occupied by red blood cells increase from the 43-37 percent to well over 50 percent on the average.
The accumulation of fluid in the lungs, blocking oxygen transport
Sub acute infantile mountain sickness
A condition found in some infants born or brought to high altitude, characterized by low oxygen levels in blood, elevated levels of polycythemia, and a high risk of mortality
A seismic sea wave
The expansion of superficial blood vessels, which increase the rate of heat loss from the body to the air.
The sensitivity of ventilation rate to hypoxic exposure
The ability to use oxygen at a fast rate
