Due to the excessive amount of fur, it is hard for furry mammals to release heat, however, it is easier for them to absorb. For example polar bears. Polar bears have a lot of fur; their fur is about two and a half to five centimetres (one to two inches) thick. A polar bears’ process of regulation of blood is called thermoregulation. Polar bears are well insulated so they tend to absorb heat very quickly. That is why polar bears move slowly and rest time to time to avoid overheating. When overheating occurs excess heat is released from the areas of the body where fur is absent of blood vessels are close to the skin. On a polar bear these areas could include; nose, ears, footpads, inner thighs and shoulders. Another example of a mammal with a lot of fur is dogs. Dogs emit heat from their body by panting. With a lot of fur, animals discover that they have limited ability to sweat and so they use heavy panting to increase evaporation through their
