How frequently it fills depends on how much excess water your body is trying to get rid of. Circular muscles called sphincters close tightly to keep urine from leaking.
The bladder holds between 10 and 14 ounces of urine comfortably in most adults. Urine is produced constantly by the kidneys and then flows into the bladder for storage. The urine is held in the bladder by a valve-like muscle called the sphincter, which is located at the base of the bladder. When the bladder becomes full, a reflex reaction occurs to empty the bladder. The sphincter muscle relaxes to open the bladder outlet and the bladder wall contracts to squeeze out the urine.
