Detailed explanation-1: -For instance, sweat glands are perceived to play an important excretory function, similar to that of the renal system, responsible for clearing excess micronutrients, metabolic waste, and toxicants from the body.

Detailed explanation-2: -Abstract. The skin excretes substances primarily through sweat glands. Several conditions have been demonstrated to be associated with diminished sweating. However, few studies have concentrated on the metabolism and excretion of sweat.

Detailed explanation-3: -Therefore, sweating is associated with excretion.

Detailed explanation-4: -Its main function is excretion of waste materials. But it have other function also. Sweat keeps the body cool as it evaporates from the skin. Another function is to control body temperature.

Detailed explanation-5: -Sweat glands in the skin secrete a fluid waste called sweat or perspiration; however, its primary functions are temperature control and pheromone release. Therefore, its role as a part of the excretory system is minimal. Sweating also maintains the level of salt in the body.
