Describe the skin when heat is applied
Homework Answers
When heat is applied to the skin, the blood vessels which are present under the skin gets dilated. This is called vasodilation. It increases blood circulation underneath the skin, where the heat is applied. The process of conduction takes place, when heat is applied to the skin. Thus the heat is conducted from outer surface of the skin to inner body structures such as tissues, muscles, bone etc. There are various means to apply heat over the skin.
