ureter

n. tube for transfer of urine from the kidneys to the bladder (Anatomy)

In human anatomy, the ureters are the ducts that carry urine from the kidneys to the urinary bladder, passing anterior to the psoas major. The ureters are muscular tubes that can propel urine along by the motions of peristalsis. In the adult, the ureters are usually 25-30cm long. In humans, the ureters enter the bladder through the back, running within the wall of the bladder for a few centimetres. There are no valves in the ureters, backflow being prevented by pressure from the filling of the bladder, as well as the tone of the muscle in the bladder wall.In the female, the ureters pass through the mesometrium on the way to the urinary bladder.
