MICROANATOMY

Detailed explanation-1: -In the urinary system, the peristaltic motion is caused by a muscular contraction of the ureteral wall initiated by pacemakers. This drives urine from the kidney to the bladder through the ureter.

Detailed explanation-2: -Ureteral Peristaltic Activity It is responsible for the transport of a variable volume of urine from the pelvis to the bladder. Normal ureteral function has two separate phases, namely, ureteral filling, which is entirely passive, and ureteral emptying, which is entirely active.
