How does the skin regulate the temperature of the body?
The skin regulates the body temperature by controlling the loss of heat from the body. Whenever the body gets heated up, the blood vessels near the skin dilate and increased blood flow brings heat to the skin’s surface. This causes the skin’s temperature to rise and loss of heat takes place from the hot skin to the cooler environment. More heat is lost from the skin when sweat evaporates carrying heat away from the skin. The sweat glands present over the entire skin surface open through ducts and dispose of waste through ducts and dispose of waste products along with sweat.
Conversely, when the body has to conserve heat, sweating stops and blood vessels constrict. This prevents the blood from carrying heat to the skin. The temperature of the skin falls down decreasing the heat loss.
In this way , the skin keeps the body temperature more or less constant.
