In human anatomy, the<unk> s are the ducts that carry urine from the kidneys to the urinary bladder, passing anterior to the psoas major. The<unk> s are muscular tubes that can propel urine along by the motions of peristalsis. In the adult, the<unk> s are usually 25-30cm long.
In humans, the<unk> s enter the bladder through the back, running within the wall of the bladder for a few centimetres. There are no valves in the<unk> s, 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<unk> s pass through the mesometrium on the way to the urinary bladder.
