Where does the upper end of each ureter flare into a funnel-shaped structure entering the kidney?

• A. Cortex
• B. Renal pelvis
• C. Renal Capsule
• D. Renal Hilum

Answer: (B)

The upper end of the ureter expands into a funnel-shaped collecting chamber inside the kidney called the renal pelvis. This structure gathers urine from the major calyces and then narrows to form the ureter as it exits the kidney. It sits at the kidney’s hilum region, but its main role is to collect and funnel urine, not to be the outer cortex, the fibrous capsule, or the entry site itself.
