Abstract

Excretion, the elimination of metabolic waste products, is a vital homeostatic process. The main excretory materials in animals are carbon dioxide and water from respiration, and nitrogen-containing wastes derived from the breakdown of surplus protein. In certain circumstances these materials may perform useful functions; for example, an animal living in hot dry conditions normally uses metabolic water to maintain its body’s water balance.
