B5__Homeostasis-and-Response The Thermoregulatory Centre which monitors and control body temperature is found in the brain. It has receptors to monitor temperature of blood and skin.

If temperature becomes too high:

  • Sweat is produced from sweat glands and evaporates off skin to transfer heat away.
  • Vasodilation. Blood vessels widen near skin increasing energy transfer away from body. Heat lost to environment.

If temperature becomes too low:

  • Sweating stops
  • Skeletal muscles rapidly contract - shiver
  • Hairs stand to create an insulating layer.
  • Vasoconstriction.
