• The ureters are tubes that come out of both kidneys. They transport urine from the kidneys down to the bladder.
• The bladder is a place to store urine. It has the shape of a balloon. and can be expanded The bladder can normally hold approximately 350–500 ml of urine. But you will begin to feel the need to urinate when you have 200–350 ml of urine while you urinate. The bladder muscles contract. This causes the sphincter to open. So that urine can flow out into the urethra
