EXCRETION Introduction Humans must get rid of two types of wastes. Wastes from the digestive system (feces) and wastes from metabolic activities (sweat & urine). Removing digestive wastes (pooping) is called egestion.
Excretion. Excretion is the process by which waste products of metabolism and other non-useful materials are eliminated from an organism. In vertebrates this is primarily carried out by the lungs, kidneys and skin. This is in contrast with secretion, where the substance may have specific tasks after leaving the cell.xcretion is an essential process in all forms of life. In humans urine is carried out through the urethra and that is part of the excretory system. In single-celled organisms, waste products are discharged directly through the surface of the cell.
