Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Skin helps the body maintain steady ____ through perpiration and the enlarging of blood vessels.
A
temperature
B
weight
C
sweat
D
water
Explanation: 

Detailed explanation-1: -The skin’s immense blood supply helps regulate temperature: dilated vessels allow for heat loss, while constricted vessels retain heat. The skin regulates body temperature with its blood supply. The skin assists in homeostasis. Humidity affects thermoregulation by limiting sweat evaporation and thus heat loss.

Detailed explanation-2: -Another important function of the skin is body temperature regulation. When the skin is exposed to a cold temperature, the blood vessels in the dermis constrict. This allows the blood which is warm, to bypass the skin. The skin then becomes the temperature of the cold it is exposed to.

Detailed explanation-3: -The sweat glands produce sweat in response to heat and stress. Sweat is composed of water, salt, and other chemicals. As sweat evaporates off the skin, it helps cool the body.

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.
