Excretion and the liver Excretion in mammals Excretion is the removal of potentially harmful or toxic substances from the body. These substances are usually waste materials produced by complex chemical reactions taking place in living cells. Enzymes catalyse the reactions.
* are responsible for the excretion of carbon dioxide and water (waste products of cellular respiration) * these are removed as gases during the process of exhalation. B) Liver. * recycles worn out red blood cells * produces urea (a semi-toxic nitrogenous waste) from the breakdown of amino acids (contains nitrogen). water (98%), salts, and a small amount of urea diffuse from the blood into sweat glands * excreted through the process of perspiration (sweating!) * main job of sweating is to maintain body temperature (cool down). * site of most urea excretion * controls the concentration of most of the body fluids.
