<P> The urinary system , also known as the renal system , consists of the kidneys , ureters , bladder , and the urethra . Each kidney consists of millions of functional units called nephrons . The purpose of the renal system is to eliminate wastes from the body , regulate blood volume and blood pressure , control levels of electrolytes and metabolites , and regulate blood pH . The kidneys have an extensive blood supply via the renal arteries which leave the kidneys via the renal vein . Following filtration of blood and further processing , wastes ( in the form of urine ) exit the kidney via the ureters , tubes made of smooth muscle fibers that propel urine towards the urinary bladder , where it is stored and subsequently expelled from the body by urination ( voiding ) . The female and male urinary system are very similar , differing only in the length of the urethra . </P>
