Homeostasis
Which of the following would be a negative feedback response by the body to hyperthermia?
Shivering
Sweating
Vasoconstriction of blood vessels in the dermis
An increase in metabolic rate
Sweating
Hyperthermia is an increase on body temperature above 38 °C. Negative feedback would be a response that opposed the temperature rise. Allowing perspiration to evaporate from the skin would cool the skin and lead to a decrease in body temperature. The effect of the other choices would be to increase body temperature.
