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
