GENERAL HISTOLOGY

Detailed explanation-1: -Regulation of body temperature: The skin has a large surface area that is highly vascularized, which allows it to conserve and release heat through vasoconstriction and vasodilation, respectively. When body temperatures rise, blood vessels dilate to increase blood flow and maximize the dissipation of heat.

Detailed explanation-2: -Our internal body temperature is regulated by a part of our brain called the hypothalamus. The hypothalamus checks our current temperature and compares it with the normal temperature of about 37°C. If our temperature is too low, the hypothalamus makes sure that the body generates and maintains heat.

Detailed explanation-3: -The blood vessels of the dermis provide nutrients to the skin and help regulate body temperature.

Detailed explanation-4: -When heat activates sweat glands, these glands bring that water, along with the body’s salt, to the surface of the skin as sweat. Once on the surface, the water evaporates. Water evaporating from the skin cools the body, keeping its temperature in a healthy range.
