adaptation, physiological

adaptation, physiological

change in the reaction that organisms show as a result of prolonged exposure to conditions that normally produce a different or more extensive reaction. For example, mountain sickness (headache, nausea, fatigue) in a human being passes off as he or she becomes acclimatized to high altitudes because of adjustments that occur in the respiratory and circulatory systems. See ACCLIMATIZATION.
