Thermoregulation: Maintenance of a constant core body temperature to maintain optimum enzyme activity

Physical Processes:

  • Exothermic chemical reactions
  • Latent heat of evaporation-objects cool down as water evaporates from a surface
  • Radiation-the transmission of electromagnetic waves to and from the air/water/ground
  • Convection-the heating and cooling by currents of air or water, warm air rises, cools then drops back down
  • Conduction-heating as a result of the collision of molecules, the ground and water are good conductors, water is not


  • Use their surroundings to warm…
