How does the body respond to an increase or decrease in temperature to maintain homeostasis?

Increase in temperature:Sweat produced from sweat glands increases energy transfer away from the body when it evaporates.Vasodilation of blood vessels close to the surface of the skin, which increases energy transfer from the body and results in heat loss.Decrease in temperature:No sweating Vasoconstriction of blood vessels close to the surface of the skin to reduce heat loss.Erector muscles connected to hair follicles contract to make the hairs stand on end. This creates an insulating layer to trap warm air.Shivering occurs when skeletal muscles contract rapidly to generate heat from respiration.
