What is a "sweat duct"?

A sweat duct is a small tube-like structure that extends from the sweat glands to the surface of the skin. It is responsible for transporting sweat, a mixture of water, salts, and other substances, from the sweat glands to the skin's surface. Sweat ducts play a crucial role in regulating body temperature by facilitating the evaporation of sweat, which helps to cool down the body. These ducts are distributed throughout the body and are particularly abundant in areas such as the armpits, palms, and soles of the feet, where sweat production is higher.
