Final answer:
The correct answer is b) Ureter, which is the tube that transports urine from the kidney to the bladder. The urethra, on the other hand, carries urine from the bladder to the outside of the body.
Step-by-step explanation:
The structure through which urine passes on its way from the kidney to the bladder is called the ureter. After urine forms in the kidneys, it first collects in the renal pelvis, and then enters the ureters, which are two muscular tubes that move the urine by peristalsis to the bladder. The bladder is a sac-like organ that stores urine until it is ready to be excreted from the body. It is important to note that the urethra is the tube responsible for transporting urine from the bladder to the outside of the body, not from the kidneys to the bladder. Therefore, the correct answer to the question is b) Ureter.
