Document Summary

Homeostasis- controlled by the hypothalamus, achieved when internal heat production and external heat loss are properly balanced. Thermoregulation- process by which the body maintains internal body temp. Two mechanisms for maintaining homeostasis: sweating- water evaporation cools the body, shivering- increase in blood flow increases body temperature. Homeostasis mechanisms are activated in two ways: stimulation of peripheral thermal receptors in the skin, changes in blood temperature as it flows through the hypothalamus. Heart rate increases and respiratory rate increases which stimulates an increase in blood flow and an increased temperature. 4. hotter to cooler object, requires direct contact (ex sitting on a chair) radiation- heat transfer from one object to another without direct contact between the objects. Talking- mucus membranes are exposed and water evaporates. The body naturally gives off water athletics and the environment. Heat stress index- measure of relative humidity, air temp, and solar radiate energy.
