Which structure transports urine from the kidney to the bladder?

• A. Urethra
• B. Renal pelvis
• C. Ureter
• D. Bladder

Answer: (C)

Urine moves from the kidney to the bladder through a muscular tube called the ureter. After urine is formed, it collects in the renal pelvis and is then propelled down the ureter by rhythmic muscular contractions (peristalsis) until it reaches the bladder, where it is stored until urination. The urethra carries urine out of the body, and the bladder serves as a storage reservoir. The renal pelvis is the kidney’s collecting region that feeds the ureter, not the long-distance transport to the bladder.
