Excretion is the process of elimination of the metabolic waste products from the body through the lungs, kidney and the skin. The urinary system consisting of a pair of kidneys and ureters, urinary bladder and urethra helps in the elimination of water soluble waste products of metabolism especially nitrogenous wastes like urea, uric acid, and creatinine in the form of urine.Gaseous wastes diffused from the blood stream such as carbon dioxide is eliminated by lungs as part of normal respiration.Sweat glands in skin are playing the role in excretion and electrolyte balance. | Excretion is the process of elimination of the metabolic waste products from the body through the lungs, kidney and the skin.
