It might not feel like it, but the adult bladder can hold as much as half a litre 2 cups of pee before you'll feel the need to 'go'. Your body knows how much is in there because your bladder wall is filled with tiny receptors that send a message to your brain when the bladder reaches capacity. Fortunately, most of us have full control over our bladder function, so when we receive this message, we can choose to either relieve ourselves right away, or hold it because it's a really long way to the bathroom from the couch. In an episode of SciShow , Michael explains that once you've made the decision that you're too busy to pee right now, the cylindrical sphincters in your bladder close up tightly to keep all of the urine from leaking through your urethra. These little muscles are great at what they do, until you make them do it consistently for a really long time, say if you're a trucker and you're holding in your pee on long trips several times a week.
