Which term describes the indentation in the kidney that serves as a passageway for the lymph vessels, nerves, renal artery and vein, and the ureter?

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

Answer: (A)

The renal hilum is the indentation on the kidney’s medial border that acts as the gateway for the structures entering and leaving the kidney—the renal artery and vein, the ureter, and the accompanying lymphatics and nerves. That passage point is what the term describes. The cortex is the outer layer of kidney tissue, not a passageway; the glomerulus is the filtering tuft inside each nephron; and the renal pelvis is the collecting area inside the kidney that funnels urine into the ureter, not the entry/exit route for vessels and nerves.
