I am your bladder! I can control urine, and later it can go down to the toilet or urinal! The kidneys can also help produce urine, then it goes down the 2 tubes called the ureters, then straight down into me. This is when the thought pops up in your brain; "Ooh! Gotta go pee!" Then, once you are at a toilet or urinal, you can finally take a whizz.
