Explain the cycle of thermoregulation in humans
- What is thermoregulation? A way to maintain the bodies temperature through feedback mechanisms to keep the temperature at 37 degrees, which is optimal for functioning. 2)What are the components of thermoregulation?The skin epidermis, hypothalamus, glands, blood vessels and nerves. The stimulus will be discovered at the level of the skin, which will then sensed by the central nervous system (CNS) The CNS will a signal to the hypothalamus which is an important region of the brain to maintain body functions such as temperature. 3)What happens when the body temperature is increased?In hot conditions, the body will sweat to allow for evaporation cooling. There is vasodilation to allow for greater blood flow towards the skin surface so heat can be released. 4)What happens when the body temperature is decreased?In colder conditions, the body would like to increase its core temperature. There is vasoconstriction to prevent heat loss. Shivering increases the temperature through movement of muscles.
