Verified step by step guidance

Understand the anatomy of the nephron, which is the functional unit of the kidney. It consists of several parts: the proximal convoluted tubule, the loop of Henle, the distal convoluted tubule, and the collecting duct.

Recognize the flow of filtrate through the nephron: it starts in the Bowman's capsule, moves to the proximal convoluted tubule, then to the loop of Henle, followed by the distal convoluted tubule, and finally into the collecting duct.

Identify the role of the collecting duct. It is responsible for receiving urine from multiple nephrons and is the final segment of the nephron where urine is concentrated.

Understand that the collecting duct is the structure that empties into the renal pelvis. The renal pelvis is a funnel-shaped structure that collects urine from the collecting ducts and channels it into the ureter.

Conclude that among the given options, the collecting duct is the correct structure that empties into the renal pelvis, as it is the last part of the nephron before urine enters the renal pelvis.
