Drops of sweat. Sweat is a liquid that is made by the skin when the body is hot. Sweat is made in sweat glands under the surface of the skin, and it comes out of tiny holes in the skin called pores. Sweat is mostly water, but it also contains some salts. The body makes sweat to cool itself down. The sweat takes the heat from the body when it evaporates (turns to gas).
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.
