Which structure carries urine from the kidneys to the bladder?

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

Answer: (A)

Urine is carried from the kidneys to the bladder by the ureters, two muscular tubes that extend from the renal pelvis of each kidney down to the bladder. They move urine downward using peristaltic waves and connect to the bladder in a way that helps prevent backflow. The bladder then stores urine, and the urethra carries urine out of the body. The renal pelvis is the funnel inside the kidney that collects urine before it enters the ureter; it doesn’t transport urine directly to the bladder.
