Document Summary

Acclimation adaptations to extreme heat or cold over the short-term (days, weeks). Acclimatization natural adaptations to extreme heat or cold over the long-term (months, years). Hemotherms internal body t is physiologically regulated kept near constant (humans). Careful balance between heat production & heat loss: disruption in balance . Converting between units of temperature measure change in body t. Small part (< 25%) of atp produced physiological functions (muscle contraction). Large part (> 75%) of atp produced converted to metabolic heat (m). M > heat-loss body stores excess heat increase in internal t. Ability to maintain constant internal t depends on ability to balance m & heat- loss. Transfer of body heat to and from the environment. Mechanism of heat-transfer: m moves from the core to the skin via the blood access to outside environment. Dry heat exchange = k + c + r. Insulation resistance to dry heat exchange (clothing, home heating).
