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.
Your bladder is the hollow muscular organ that stores your urine. It's a bit like a floppy balloon â as your bladder fills, it expands to store the urine. On average, your bladder can hold 400 to 600ml of urine for up to about five hours. The muscle in your bladder wall is called the detrusor muscle. The detrusor muscle relaxes to allow your bladder to fill. When you go to the toilet, it contracts to squeeze out urine.
