The part of the mammalian skin involved in excretion is the sweat glands. Sweat glands are responsible for producing sweat, which contains water, salt, and other waste products such as urea and ammonia. These waste products are eliminated from the body through the skin via the sweat glands. Sweat glands help to regulate body temperature and maintain electrolyte balance by excreting excess water and salt from the body. Therefore, the sweat glands play an essential role in the excretion of waste products from the body through the skin.
