The bladder is expandable and stores the urine until it can be conveniently disposed of. It also closes openings into the ureters so that urine cannot flow back into the kidneys. The tube through which the urine flows out of the body is called the urethra.
Kidneys are also largely responsible for maintaining the water balance of the body and the pH of the blood. Kidneys play important roles in other bodily functions, such as releasing the hormone producing protein that stimulates increased development of red blood cells in the bone marrow, and helping to control blood pressure.
