The ureters have which primary function?

• A. Store bile
• B. Filter blood
• C. Transport urine from kidneys to bladder
• D. Produce urine

Answer: (C)

Ureters act as the conduits that move urine from the kidneys to the bladder. They achieve this with rhythmic peristaltic contractions of their smooth muscle, pushing urine downward through gravity and waves of motion. This transport role is distinct from other tasks in the urinary system: bile storage is a liver/gallbladder function; filtering blood happens in the kidneys; producing urine also occurs in the kidneys. So the ureters’ primary function is to transport urine from the kidneys to the bladder.
