Detailed explanation-1: -The skin plays a role in excretion through the production of sweat by sweat glands. Sweating eliminates excess water and salts, as well as a small amount of urea, a byproduct of protein catabolism. The liver is a very important organ of excretion.
Detailed explanation-2: -Sweat glands in the skin also serve an excretory function because water and urea are excreted in perspiration. It breaks down some wastes before they can be excreted.
Detailed explanation-3: -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.
