What is the name of the slender tube that transports urine from the kidney to the bladder?

The slender tube that transports urine from the kidney to the bladder is known as the ureter. Each kidney has its own ureter, which functions as a conduit for urine produced in the kidney to travel down to the bladder for storage.

The ureters are muscular tubes that actively contract in a process called peristalsis to help move the urine along, ensuring it reaches the bladder without obstruction. This is distinct from other structures involved in the urinary system, such as the urethra, which carries urine from the bladder to the outside of the body, and the renal pelvis, which collects urine from the kidney before it enters the ureters. The bladder neck is a region that helps in controlling the flow of urine out of the bladder but does not play a role in transporting urine from the kidneys. Hence, the anatomy and function of the ureter are essential for understanding the urinary system's operation.
