Sweat glands
Medical expert of the article
Last reviewed: 07.07.2025
Sweat glands (glandulae sudoriferae) are simple, tubular, and located in the deep sections of the dermis, where the initial section is coiled into a ball. A long excretory duct penetrates the skin and epidermis proper and opens on the surface of the skin with an opening - a sweat pore. Sweat glands are unevenly distributed in the skin. There are many of them in the armpit and groin areas, in the skin of the palms and soles. In some places, sweat glands are absent (the head and inner surface of the foreskin of the penis, the transitional part of the lips). Sweat glands, along with water, remove metabolic products from the body: urea, some salts, uric acid. Evaporation of sweat leads to a decrease in body temperature.
