GENERAL HISTOLOGY

Detailed explanation-1: -Sweat is produced by glands in the deeper layer of the skin, the dermis. Sweat glands occur all over the body, but are most numerous on the forehead, the armpits, the palms and the soles of the feet. Sweat is mainly water, but it also contains some salts. Its main function is to control body temperature.

Detailed explanation-2: -While sweating doesn’t burn fat, the internal cooling process is a sign that you’re burning calories. “The main reason we sweat during a workout is the energy we’re expending is generating internal body heat, ” Novak says. So if you’re working out hard enough to sweat, you’re burning calories in the process.

Detailed explanation-3: -Sweat glands are used to regulate temperature and remove waste by secreting water, sodium salts, and nitrogenous waste (such as urea) onto the skin surface. The main electrolytes of sweat are sodium and chloride, though the amount is small enough to make sweat hypotonic at the skin surface.
