Temperature control
What this topic asks you to be able to do
- Identify the following on a diagram showing skin: sweat glands, hairs and hair erector muscles, blood vessels, receptors, sensory neurones and fatty tissue
- Describe the function of insulation in keeping mammals' internal body temperature constant
- Describe what the hypothalamus and the skin's temperature receptors each do to keep mammals' internal body temperature constant
- Explain the part each of these processes plays in keeping a mammal's internal body temperature constant: shivering; sweating; the contraction of hair erector muscles; and vasodilation and vasoconstriction in the arterioles that supply capillaries at the skin surface
