Detailed explanation-1: -The primary role of eccrine sweat is thermoregulation through the release of latent heat from the evaporation of water. Additional functions of eccrine glands include excretion of water and electrolytes, and acidification of the skin, which prevents the colonization and growth of microorganisms.

Detailed explanation-2: -The kidneys Materials eliminated via the kidney include nitrogenous waste products (ammonia, uric acid, urea, creatine, creatinine, and amino acids), excess quantities of salts and water that may be taken into the body, and various other organic materials produced by life-sustaining chemical reactions.

Detailed explanation-3: -The sweat glands produce sweat which contains sodium chloride, amino acids, water, and glucose. The sebaceous glands excrete excess fat such as sterol and wax.

Detailed explanation-4: -The skin also acts as an excretory organ. It is estimated that 3 to 4 million eccrine sweat glands which together roughly weigh the same as one kidney (i.e., 100 g) are distributed over almost the entire human body surface.

Detailed explanation-5: -Bile is the excretory product produced in the liver, it helps in maintaining the chemical levels in the blood and removing the waste away with digestive wastes. These are eliminated from the body and thus help in excretion. It maintains the level of amino acids in the blood.
