Our body also generates heat. The heat from our body is lost or expelled from the body in various different methods. Let us know how our body expels heat.
Ways through which heat is expelled from the human body
The four channels through which heat loss occurs from the body are as follows:
Lungs
Heat loss occurs through the warm air that is breathed out which can be felt by blowing gently on the back of your hand, with the mouth wide open. Vapourization of water from the lungs also causes heat loss
Skin
Nearly 85% of the heat loss takes place through the skin by conduction, convection, radiation and through evaporation of sweat
Foods
When cold stuff is taken into the body, heat is lost
Faeces and urine
Elimination of substances takes place at a body temperature
