Urine passes through which of the following structures in the correct order?

The correct order in which urine passes through the structures of the urinary system is from the collecting duct, to the renal pelvis, then to the ureter, followed by the bladder, and finally out through the urethra.

This sequence accurately represents the journey of urine as it is produced and excreted. Urine is formed in the nephron of the kidney and collects in the collecting ducts. From the collecting ducts, it flows into the renal pelvis, which serves as a funnel for urine to enter the ureter. The ureters then transport the urine to the bladder, where it is stored until it is ready to be excreted. When the bladder is full, urine passes out of the body through the urethra.

Understanding this pathway is vital in comprehending the functionality of the urinary system, particularly how the structures interact during the process of urine formation and elimination. The incorrect options misrepresent this specific sequence, leading to a misunderstanding of the urinary tract's organization and function.
