Since evolution began Man has spread to all areas of the globe, his ability to regulate his body temperature independently of his external surroundings contributes significantly to this success. This assignment will discuss the methods by which heat is exchanged, the effect of this exchange on the body and how it is utilised in thermoregulatory mechanisms. The importance of these regulatory measures will be demonstrated by a brief description of the effects on the body …

Mans ability to control temperature in this fashion has allowed him to spread across the world, surviving extremes of temperature anywhere from arctic to dessert.
