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. The liver breaks down many substances in the blood, including toxins.
Detailed explanation-2: -Kidneys and skin help in the removal of excess salts from the body. Sweat glands regulate temperature and remove excess water, sodium salts, and nitrogenous wastes (such as urea) onto the skin surface.
