Heat Lost

Heat is lost from the body via the skin, lungs and excretions. The most

important route of heat loss is via the skin. Depending on external and

internal circumstances, about 85 percent of heat loss occurs in this

way. The average heat loss of the average male adult is equivalent to

that of a 60-watt electric valb. Heat is lost via the skin in the three

ways: namely, conduction, convection and radiation.
