GENERAL HISTOLOGY

Detailed explanation-1: -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-2: -The skin releases sweat through sweat glands present in the body. The sweat evaporates and helps to keep the body cool when it is warm outside. Skin assists in the process of excretion through sweating by eliminating water, salts and urea.

Detailed explanation-3: -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-4: -Organs of excretion include the skin, liver, large intestine, lungs, and kidneys. All of them excrete wastes, and together they make up the excretory system .

Detailed explanation-5: -Although the kidneys are the main organs of excretion, several other organs also excrete waste s. They include the large intestine, liver, skin, and lungs. All of these organs of excretion, along with the kidneys, make up the excretory system.
