Thermoregulation

Physical Adaptations
  • Fur, hair, etc to insulate heat

Circulatory Adaption
  • Countercurrent flow

Behavioural Adaption
  • Gross muscle movements
  • huddling
  • relocation
  • torpor

Physiological Changes
  • Regulating rate of heat exchange through vasoconstriction and vasodilation
  • Regulating rate of heat production through muscle contractions and shivering
  • Regulating rate of metabolic heat production
