Waste matter. The elimination of waste products from the body.
The removal of the waste products of metabolism from the body, mainly through the action of the kidneys. Excretion also includes the loss of water, salts, and some urea through the sweat glands and carbon dioxide and water vapor from the lungs, and the term is also used to include the egestion of feces.
The process by which the residue of undigested food in the gastrointestinal tract (faeces) and the waste products of the body’s metabolism mainly as urine via the kidneys, but also as sweat from the skin, and water and carbon dioxide from the lungs are eliminated.
The process by which the body collects and removes wastes produced by its cells.
Excretion refers to the process of eliminating any waste material from the body. Such waste materials could include by-products of digestion, remnants from tissue repair, and surplus water.
The kidneys are responsible for the excretion of urine, which includes excess nitrogen (in the form of urea), along with surplus water, salts, certain acids, and most medications. The liver discharges bile, laden with waste products and bile pigments resulting from the breakdown of red blood cells, some of which is expelled from the body via feces. The large intestine gets rid of undigested food, certain salts, and extra water as feces. The lungs release carbon dioxide and water vapor into the atmosphere. Sweat glands excrete salt and water onto the skin’s surface as a means to regulate body temperature.
