Ureter Peristalsis: How Circular Muscles Move Urine to the Bladder #97933 (License: Personal Use)

The image depicts a cross-section of the ureter, highlighting the role of circular smooth muscle layers in peristaltic movement. A visible orange bolus represents urine being propelled downward as adjacent segments alternately contract and relax. This coordinated action prevents backflow and ensures unidirectional transport to the bladder.

Used in medical education, urology resources, or patient-facing health content to explain urinary tract physiology; matches user intent to understand how urine moves from kidneys to bladder.
