GENERAL HISTOLOGY

Detailed explanation-1: -Excretion is the process of removing wastes and excess water from the body. It is one of the major ways the body maintains homeostasis. Organs of excretion make up the excretory system. They include the kidneys, large intestine, liver, skin, and lungs.

Detailed explanation-2: -These chemical reactions produce waste products such as carbon dioxide, water, salts, urea and uric acid. Accumulation of these wastes beyond a level inside the body is harmful to the body. The excretory organs remove these wastes. This process of removal of metabolic waste from the body is known as excretion.

Detailed explanation-3: -Excretion is the process where all the metabolic wastes are removed from the body. Excretion in humans is carried through different body parts and internal organs in a series of processes. Diffusion is the most common process of excretion in lower organisms.

Detailed explanation-4: -The excretory system helps maintain homeostasis because it removes toxins from the body and keeps concentrations of nutrients, minerals, and water stable. Homeostasis is a steady, internal state in the body.
