Describe how the body responds when a decrease in core body temperature is detected. (6 marks)
When the core body temperature falls below the optimum, vasoconstriction occurs meaning blood flow to the vessels supplying the skin is reduced. This is beneficial as it reduces lost energy. The body also responds by shivering since this increase in muscle contractions allows more energy to be released by respiration.
