ANATOMY

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: -Peristalsis is a series of muscle contractions. These contractions occur in your digestive tract. Peristalsis is also seen in the tubes that connect the kidneys to the bladder.

Detailed explanation-3: -A series of normal coordinated, rhythmic muscle contractions, that occurs automatically to move food through the digestive tract is called peristalsis.

Detailed explanation-4: -Ureteral peristalsis can be considered as a series of compressive zones, corresponding to waves of active muscular contraction, that move at near-constant speed along the ureter towards the bladder.
