Which of the following statements about the ureters is correct?

The ureters play a crucial role in transporting urine from the kidneys to the bladder, and they possess the ability to perform peristalsis, which is a series of wave-like muscle contractions. This movement is essential for pushing urine downward, even against the force of gravity. The process mirrors peristalsis in the gastrointestinal tract, where similar muscular contractions help move food through the digestive system. This capability allows the ureters to effectively manage urine flow, ensuring that it reaches the bladder in a controlled manner.

This understanding highlights the active role that the ureters have in urine transport, distinguishing them from mere passive conduits that would rely solely on gravity. This is why the statement regarding the ureters' capability of peristalsis is accurate.
