Which structure allows urine to travel from the kidney to the bladder?

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

Answer: (A)

Urine moves from the kidney to the bladder through the ureters. After urine collects in the kidney’s renal pelvis, it enters the ureter, a muscular tube that uses rhythmic peristaltic contractions to propel urine downward into the bladder. The bladder then stores it, and the urethra handles its exit from the body. The renal pelvis is the kidney’s collecting area that feeds the ureter, not the conduit to the bladder.
