Homeostasis - keeping your internal body conditions constant

Body temperature must be maintained at 37

Too high (above 40) - heat stroke/dehydration - enzymes denature

Too low (below 35) - hypothermia - enzymes work too slowly

We LOSE heat by:

  • Radiation - from our skin surface
  • Conduction - by toughing cold objects or water
  • Evaporation of water - sweat/wet skin

We can help by:

  • Reducing exercise
  • Wearing fewer clothes
  • Increasing blood flow to the surface (vasosdilation)
