Controlling Body Temperature

Homeostasis - keeping your internal body conditions constant

Body Temp. - 37

Too high - 40, heat stroke, dehydration

Too low - 35, hypothermia

37 is the optimum body temp. for the enzymes in your body

At high temperatures the enzymes denature (change shape)

At low temperatures they work too slowly

We lose heat by:

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