- Thermoregulation
- Too Hot
- sweat released from sweat glands under the skin
- released from sweat glands under the skin
- covers outer later of skin
- heat energy transferred to the water and evaporates when it has enough energy
- takes heat energy when it evaporates
- lowers temperature
- hairs lie flat
- hair erector muscle relaxes
- blood vessels dilate
- allow more blood to enter capillaries that pass close to skin surface
- vasodilation
- sweat released from sweat glands under the skin
- Too Cold
- shivering
- muscles start to contract automatically
- needs energy
- generated through respiration
- produces heat to increase body temperature
- generated through respiration
- hairs stand on end
- hair erector muscle
- trap an insulating layer of air around the body
- blood vessels constrict
- reduce blood flow in capillaries near to skin surface
- vasoconstriction
- shivering
- Too Hot
