The ureters are a pair of muscular, tubular structures responsible for taking urine from the kidneys to the urinary bladder for storage, prior to excretion. They are collapsible S ­shaped channels, each about 25 cm in length. They are widest at the renal pelvis and narrow progressively as they enter the urinary bladder.

The lumen of each ureter is lined by a mucosal layer of transitional epithelium that accommodates the increase in pressure when the volume of urine leaving the kidney increases, minimizing the risk of rupturing the ureters. These conduits have several in­foldings caused by multiple layers of smooth muscle throughout the ureteral wall.

In this video, we explore the anatomy of the ureters in detail. You’ll learn about the function of the ureters, as well as their location, arterial supply, venous drainage, neuronal supply and lymphatic drainage. Check out the timestamps below to jump to specific points in the video:
