After urine leaves the kidney via the collecting tubules, the calyces and the renal pelvis, it enters the ureter.
The ureter carries urine from the kidney to the bladder. It is lined with transitional epithelium that is usually 4-6 cells thick.
A thick lamina propria is also present.
The epithelial layer is supported by an internal longitudinal layer and an outer circular layer of smooth muscle.
The lumen of the ureter is star shaped.
This cross section shows these layers of the ureter.
The transitional epthelium of the ureter can be better appreciated in this higher magnification view.
