PATHOLOGY

Detailed explanation-1: -The hypothalamus works with other parts of the body’s temperature-regulating system, such as the skin, sweat glands and blood vessels-the vents, condensers and heat ducts of your body’s heating and cooling system.

Detailed explanation-2: -Increasing the amount and speed of blood flowing to and within the skin by widening the blood vessels (vasodilation) allows more heat to be lost thereby reducing body temperature. Narrowing the blood vessels (vasoconstriction) means less heat will be lost this way thereby maintaining the core temperature of the body.
