The expanded beginning of the ureter connects to the
A) renal sinus.
B) renal pelvis.
C) renal calyx.
D) renal hilum.
E) renal corpuscle.

Accepted Answer

The renal pelvis is the expanded beginning of the ureter. The renal pelvis is the funnel-shaped structure that collects urine from the major and minor calyces and drains it into the ureter. The renal pelvis is located in the renal sinus, which is a cavity within the kidney. The renal calyces are cup-shaped structures that collect urine from the renal pyramids. The renal hilum is the area where the renal artery, renal vein, and ureter enter and exit the kidney. The renal corpuscle is the initial filtering component of the nephron.
