  • Via the lungs in breath
  • Via the heart in circulation

3. Why does the human body's temperature need to be kept around 37 degrees Celsius?

4. Why do we sweat a lot when we are cold?

  • Trick question: The body produces very little sweat when we are cold as the sweat gets rid of some heat in the body when it evaporates and the body needs heat at that moment
  • It causes our hairs to stand up and trap in insulating air
  • Because sweating generates heat in the body
  • Sweating triggers the effectors in the body to shiver

  • So that very little sweat gets produced
