We were talking about the subject with my friends, anyone care to enlighten us where does the pee go?
In: Biology
During the day, that’s how much it can hold.
Holds more at night because you’re relaxed.
You can hold more because it can expand like a balloon.
But you should be going about that same volume for health reasons.
For Americans, 2 cups per session during the day and 4 cups at night.
I’ve drained up to 2L out of a bladder. It can definitely hold more than 600ml, although it’s really not good for your bladder to be that full.
Your bladder can hold more than that. I’ve voided 1,000 mL before. You probably shouldn’t be holding urine so long that you need to void more than 500 mL , however.
Your body holds a ton of water, for a 160lb person, assuming that you are around 60%-65% water that means about 96-100(ish) pounds of water or 42-45 liters. About 6 of those are in your circulatory system, which is constantly being filtered through your kidneys to produce urine. There’s tons of beautifully intricate mechanisms balancing intracellular, extracellular and intravascular fluid and electrolyte levels in your body, so if your fluid levels are high enough you can pretty quickly produce a lot of urine.
Your bladder and bloodstream.
Your stomach is not a bag of fluid. Your intestines allow water into the bloodstream. The blood circles your body.
Independently, a completely different mechanism in your kidney filters the blood and, if it’s problematic, filters out the excess water and puts it into the bladder. The bladder is what makes you want to pee, and where the pee comes from.
Even Wiki will tell you in the first paragraph – after 300-500ml your bladder will want to empty, but it can hold far more.

This is also why you can die by drinking too much water too fast… it will water down your blood quicker than your kidneys can deal with it.
