Sweat glands in the skin consist of coiled tubes that originate in the deeper dermis or superficial subcutaneous layer.
Sweat glands are a type of simple tubular skin gland that secretes perspiration. They are found in almost every area of the human body and typically consist of an epithelial tube that spirals down from a tiny skin pore into the dermis or subcutaneous tissues before coming to a point where it forms a tuft.
Although sweat glands are found throughout the body, they are most prevalent on the forehead, armpits, palms, and soles of the feet. While salts do appear in sweat, water makes up the majority of it. Its primary job is to regulate body temperature. The skin's surface cools when the water in the perspiration evaporates.
There are two different kinds of sweat glands: Eccrine glands, which are present throughout the body and release a watery substance to cool the skin. The armpits and the perianal region are the principal locations for apocrine sweat glands, which release a more viscous, pungent substance.
