The kidneys and liver carry out detoxification, altering toxic substances into forms that are not poisonous to the body. The process of maintenance of osmotic and ionic concentration of body fluids is called osmoregulation. Excretion is the process by which metabolic wastes 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. Excretion is an essential process in all forms of life. For example, in mammals urine is expelled through the urethra, which is part of the excretory system. In unicellular organisms, waste products are discharged directly through the surface of the cell.
