Controlling Body Temperature

• the hypothalmus is the part of brain monitoring and controls body temperature
• temperature receptors are found on the surface of the skin and hypothalmus
• the optimum temperature is 37C
• if the temperature is too high

  • temperature receptors detect body temperature is high
  • thermoregulatory centre receives information triggering effectors
  • effectors respond by sweating , hairs lie flat and blood vessels dilate (vasodilation)
• if the temperature is too low

  • temperatures receptors detect body temperature is too low
  • thermoregulatory centre receives information triggering effectors
  • effectors respond by shivering , hairs stand up , blood vessels constrict (vasoconstriction)
