What is the name of the tubes that transport urine from the kidneys to the bladder?

The tubes responsible for transporting urine from the kidneys to the bladder are known as ureters. Each kidney has its own ureter, which functions as a conduit for urine produced by the kidneys to travel to the urinary bladder for storage before being expelled from the body. Ureters have muscular walls that help propel urine through peristalsis, a rhythmic contraction that moves urine efficiently.

The other choices refer to different structures in the urinary system that perform separate functions. The urethra is the tube through which urine exits the body from the bladder; renal tubules are parts of the nephron in the kidneys where urine formation begins; and the bladder is the organ that stores urine before it is expelled. Understanding the specific roles of each part of the urinary system is essential for recognizing how urine is formed, transported, and eliminated.
