GENERAL HISTOLOGY

Detailed explanation-1: -When exposed to hot conditions, sweating is one of the primary methods your body uses to control its temperature. Sweat, as it evaporates, helps cool the skin. Blood vessels feeding the skin also dilate, which allows warm blood to flow to the skin surface. This helps remove heat from the body core.

Detailed explanation-2: -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-3: -By changing the blood flow to the skin, the body can control heat exchange at its surface with its surroundings. 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.
