Ais a tubular organ that transports urine from a kidney to the urinary bladder.

The answer to this question would be: ureter

Ureter is the long tubular duct made of epithelial cell that connects the kidney and the bladder. Urine will pass through the ureter to go into the bladder. Urine flow might be obstructed if there was a stoned formed in the kidney. In this case, the patient might feel colic pain to the flank. Urethra will be the tubular organ that goes from the bladder to penis/vagina.

No but I’ll take the free points for answering
