Final answer:
The structure that transports urine to the bladder by peristaltic action is the ureter.
Step-by-step explanation:
The structure that transports urine to the bladder by peristaltic action is the ureter.
Ureters are tube-like structures that connect the kidneys with the urinary bladder. The walls of the ureter contain smooth muscle that can contract to push urine through the ureter by peristalsis.
The urethra, on the other hand, transports urine from the bladder to the outside of the body for disposal.
