Corrective Responses to an Increase in Body Temperature: Sweat glands activated, Body heat used to evaporate water in sweat, Vasodilation, Increased blood flow to the skin, Hair erector muscles relax, Hair lies flat, Decreased metabolic rate, Less heat produced, No shivering, Corrective Responses to a Decrease in Body Temperature: No sweating, Vasoconstriction, Decreased blood flow to skin, Hair erector muscles contract, Hair traps layer of insulating air, Muscle contractions so generate heat (shivering), Increased metabolic rate, More heat produced,
