The renal papilla is the tip of the renal pyramid in the kidney, where urine is excreted from the kidney's functional units, the nephrons. Each renal pyramid contains multiple nephrons that filter blood and produce urine, which then drains into small ducts called collecting ducts. These ducts converge at the renal papilla, where the urine is released into the minor calyx. The renal papilla is crucial in the final step of urine formation, as it serves as the point where the urine moves from the kidney’s internal structures to the larger collecting system, ultimately reaching the ureter.
