Final answer:
The ureter is the tube that connects each kidney to the urinary bladder. Ureters are tube-like structures responsible for carrying urine from the kidneys to the bladder using peristalsis.
Step-by-step explanation:
The tube that connects each kidney to the urinary bladder is the ureter. Ureters are tube-like structures that arise at the renal pelvis of each kidney and travel down through the abdomen to the urinary bladder. They are responsible for carrying urine from the kidneys to the bladder using peristalsis, which is a series of muscle contractions.
