The bladder stores urine until you are ready to empty it. It swells into a round shape when it is full and gets smaller as it empties. A healthy bladder can hold up to 16 ounces (2 cups) of urine comfortably. How frequently it fills depends on how much excess water your body is trying to get rid of.
Urine drains from your kidneys to your bladder through tubes called ureters. 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. MOST POPULAR.
