Quizplus · Accepted Answer

The dilated, proximal portion of the ureter shown in the image is called the renal pelvis. It is located at the hilum of the kidney and serves as a funnel-shaped reservoir for urine before it enters the ureter to be transported to the bladder. The calyces and the renal pelvis together form the collecting system of the kidney. The trigone is a region in the bladder and is not related to the anatomy shown in the image.
