12.2 Regulation of body temperature

Mechanisms of heat loss and gain

Methods of gaining heat include:
- Production of heat by the metabolism of food during respiration
- Gain of heat from the environment by conduction, convection and radiation. 

Methods of losing heat include:
- Evaporation of water (sweating)
- lossof heat to the environment by conduction, convection and radiation. 

Conduction = the transfer of energy through matter from particle to particle. Heat causes the particles to vibrate
