Verified step by step guidance

Step 1: Begin by understanding the anatomy of the kidney. The kidney is divided into several regions, including the renal cortex, renal medulla, and renal pelvis. The renal medulla contains structures called renal pyramids, which end in the renal papilla.

Step 2: Learn the flow of urine within the kidney. Urine is produced in the nephrons and flows through the collecting ducts, which converge at the renal papilla. The renal papilla is the tip of the renal pyramid where urine exits into the next structure.

Step 3: Identify the structure that directly receives urine from the renal papilla. The minor calyx is the first structure that collects urine from the renal papilla. Each renal papilla is associated with a minor calyx.

Step 4: Understand the progression of urine flow after the minor calyx. Multiple minor calyces merge to form a major calyx, and then the major calyces converge into the renal pelvis.

Step 5: Recognize the role of the ureter. The renal pelvis funnels urine into the ureter, which transports it to the bladder. However, the ureter does not directly receive urine from the renal papilla.
