Verified step by step guidance

Understand the anatomy of the kidney: The kidney is divided into several regions, including the renal cortex (outer layer), renal medulla (inner layer), and renal pelvis (central collecting area). The renal pyramids are located in the medulla and contain ducts that transport urine.

Learn the function of the renal pyramids: The renal pyramids contain collecting ducts that drain urine into funnel-shaped structures called minor calyces. These structures are the first point of urine collection after it leaves the ducts.

Identify the role of minor calyces: Minor calyces collect urine from the renal pyramids and transport it to larger structures called major calyces, which then funnel the urine into the renal pelvis.

Clarify the role of other structures: The renal cortex is involved in filtration and does not collect urine. The renal pelvis is a larger structure that collects urine from the major calyces and directs it to the ureters. The ureters transport urine from the kidney to the bladder.

Conclude that the minor calyces are the correct answer: Based on their anatomical location and function, minor calyces are the funnel-shaped structures that collect urine directly from the ducts of the renal pyramids.
