What is the primary function of the ureters within the human urinary system?

Explanation

The ureters are a pair of thin, muscular tubes whose primary function is to carry urine, once it has been produced by filtration within each kidney, down toward the urinary bladder for temporary storage. The walls of the ureters contain muscle tissue that contracts rhythmically in a wave-like motion, helping to actively propel urine along its path toward the bladder rather than relying purely on gravity. This is distinct from the kidneys themselves, which perform the actual filtering process, and the bladder, which stores the urine once it has arrived.
