What is the most important function of sweating?
A
to remove excess heat from the body
B
to remove excess sals from the body
C
to remove excess urea from the body
D
to remove excess water from the body
Explanation: 

Detailed explanation-1: -Its main function is to control body temperature. As the water in the sweat evaporates, the surface of the skin cools. An additional function of sweat is to help with gripping, by slightly moistening the palms.

Detailed explanation-2: -That’s because cooling your body via sweating relies on a principle of physics called “heat of vaporization.” It takes energy to evaporate sweat off of your skin, and that energy is heat. As your excess body heat is used to convert beads of sweat into vapor, you start to cool down.

Detailed explanation-3: -Sweating is the release of liquid from the body’s sweat glands. This liquid contains salt. This process is also called perspiration. Sweating helps your body stay cool. Sweat is commonly found under the arms, on the feet, and on the palms of the hands.

Detailed explanation-4: -Sweating plays an important role in the regulation of human body temperature through dissipating thermal energy from the skin surface when water in the sweat evaporates. Sweat counteracts heat stress after we exercise and allows us to survive in extreme climates.

Detailed explanation-5: -Solution : The sweat from sweat glands spreads on the surface of the skin. It evaporates due of the heat and at that time, it draws heat from the body. As the evaporation takes place rather, more and more heat is absorbed and then body becomes cooler. Thus sweating helps to lower the temperature of the body.
