n. the watery fluid secreted by the *sweat glands. Its principal constituents in solution are sodium chloride and urea. The secretion of sweat is a means of excreting nitrogenous waste; at the same time it has a role in controlling the temperature of the body – the evaporation of sweat from the surface of the skin has a cooling effect. Therefore an increase in body temperature causes an increase in sweating. Other factors that increase the secretion of sweat include pain, nausea, nervousness, and drugs (*diaphoretics). Sweating is reduced by colds, diarrhoea, and certain drugs. Anatomical name: sudor.
