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.
1 For most people, the bladder can hold as much as 16 ounces of urine at a time and it gets bigger and smaller depending on how much fluid is in it. 2  When it is time to urinate, the brain sends messages telling the bladder to contract and push the urine through the urethra and out of the body.
