Which tube carries urine from the kidney to the bladder?

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

Answer: (C)

Urine moves from the kidney to the bladder through a muscular tube called the ureter. The ureter begins at the renal pelvis inside the kidney, then travels to the bladder, using rhythmic contractions (peristalsis) to push urine downward even when you’re standing or moving. The bladder serves as a stretchy storage sac for urine, and the urethra is the pathway that carries urine out of the body after urination. The renal pelvis is the funnel inside the kidney that collects urine before it enters the ureter, so it’s not the tube that carries urine to the bladder, and the urethra’s role is excretion, not transport to the bladder.
