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.
PASSING WATER: One hour. On average, it takes an hour for liquid to be absorbed through the gut into the bloodstream, then filtered by the kidneys and sent to the bladder as urine, says Rowland Rees, consultant urological surgeon at the Royal Hampshire County Hospital, Winchester.
