Physiological:
- Sweat glands in skin- alter sweat secreted (water in sweat evapourates using heat from blood to supply latent heat for vapourisation)
- Lungs, mouth, Nose- panting increases evapouration using latent heat
- Hairs on skin- insulation- less heat lost by convection and radiation
- Arterioles leading to capillaries in skin- vasoconstriction/dilation - heat lost by radiation
- Liver cells- metabolism altered-exothermic reactions generate heat
- Skeletal muscles- spontaneous contractions(shivering)-heat via muscle cell respiration
Behavioural:
- Move into Shade/Burrow or Sunlight
- Orientate body to or away from sun
- Move or spread limbs, curl up (when really cold)
Thermoregulatory centre in Hypothalamus in charge of temperature regulation- peripheral temperature receptors in skin detect changes in extremities.
