Quizplus · Accepted Answer

The movement of urine from the kidneys to the urinary bladder through the ureters is due to the peristaltic contraction of the smooth muscles of the ureters, which propel the urine forward. This is a type of muscular movement that passes the urine from one organ to another. Other choices, such as active transport, gravity, and negative pressure, are not involved in this process.
