Purpose: To understand how the skin cools the body. The skin is a complex organ that has many functions to protect our bodies. One of them is controlling our body tempurature. For more about the human skin see Science of the Skin for Kids.
Mammals are warm-blooded creatures and must always maintain a fairly constant internal temperature. A difference of a few degrees can mean the difference between life and death. When your internal temperature rise, your brain signals your blood to step up circulation to the skin. In this way, the heat is carried to the surface where it is lost by radiation. Your sweat glands also spring into action and your body begins to perspire through your skin’s pores. The sweat evaporates on your skin and you cool off.
