Urine for a treat!

the b-b-b-b-b-b-bladder!

The bladder stores your pee until you're ready to go! Most bladders hold approximately 300-400 milliliters of liquid, about the size of a can and a half of soda. Drink up! When you pee, your brain tells the muscles in your bladder to tighten and squeeze out the urine. In Japanese, the word for bladder, ukibukuro, also means "life buoy!' Let the bladder take out the trash with a lovely golden shower!

(But for the record: My bladder clearly holds more than a can and a half of soda... duh! I mean- come on! Would my diet coke & coffee consumption stand for that kind of nonsense? Didn't think so!)
