Homeostasis-Body Temperature

Controlling body temperature requires :

  • receptors in the skin to detect the external temperature
  • receptors in the brain to measure the temperature of the blood
  • the brain which acts as a processing centre, to receive information from the temperature receptors
  • effectors (sweat glands and muscles) to carry out the automatic response.

 If your body temperature is too high, heat needs to be transferred to the environment. This is done by sweating, since evaporation from the skin requires heat energy from the body.

If your body temperature is too low, your body will start to shiver. Shivering is the rapid contraction and release of muscles.
