What is the correct order of urinary system structures from urine formation to elimination?

• A. Kidneys; Ureters; Urethra; Bladder
• B. Kidneys; Bladder; Ureters; Urethra
• C. Kidneys; Ureters; Bladder; Urethra
• D. Ureters; Kidneys; Bladder; Urethra

Answer: (C)

Urine travels through a fixed path: it is produced in the kidneys, moves down the ureters to the bladder where it is stored, and finally exits the body through the urethra. This makes the correct sequence kidneys, then ureters, then bladder, then urethra. If the order places the bladder before the ureters or the urethra before storage, it doesn’t match how urine actually moves from formation to elimination.
