During the sweat test , medicine that causes a person to sweat is applied to the skin (usually on the arm or thigh). The sweat is then collected on a paper or a gauze pad, and the amount of salt chemicals in the paper or gauze is measured in a lab. Generally, chloride (sweat chloride) is measured.
Best Answer: The sweat glands (sudoriferous glands) in skin secrete sweat which evaporates off of the skin. Evaporation has a cooling effect. The blood vessels of the skin can dilate or constrict to either retain or dissipate heat. When they dilate, more blood is brought to the skin surface. Combined with the evaporation of sweat, this blood is cooled as it gives off heat to the environment.
