Renal papilla

1. Renal triangle 2. Efferent artery 3. Renal artery 4. Renal vein 5. Renal hilum 6. Renal pelvis 7. Ureter 8. Minor calyx 9. Renal capsule 10. Inferior renal capsule 11. Superior renal capsule 12. Afferent vein 13. Nephron 14. Minor calyx 15. Major calyx 16. Renal papilla 17. Renal column

Frontal section through the kidney.

In the kidney, the renal papilla is the location where the Medullary pyramids empty urine into the renal pelvis. Histologically it is marked by medullary collecting ducts converging to channel the fluid. Transitional epithelium begins to be seen.
