Verified step by step guidance

Begin by understanding the anatomy of the kidney, which is responsible for filtering blood and producing urine. The kidney contains structures that collect and transport urine.

Identify the role of the collecting duct. It is the initial structure where urine is collected after being filtered through the nephron. The collecting duct channels urine into the minor calyx.

Next, recognize the minor calyx as the structure that receives urine from the collecting duct. It acts as a small funnel that channels urine into the major calyx.

Understand the function of the major calyx, which collects urine from multiple minor calyces. It serves as a larger funnel that directs urine into the renal pelvis.

Finally, the renal pelvis is the central collecting region within the kidney. It gathers urine from the major calyces and channels it into the ureter, which transports urine to the bladder.
