After urine is formed in the kidneys, it passes into the ureters as the next step in the urinary system. The ureters are tubes that transport urine from each kidney to the bladder. This movement is facilitated by peristaltic contractions of the smooth muscle in the walls of the ureters, allowing for efficient flow of urine.

In this sequence, urine first needs a pathway to exit the kidneys, which is precisely the role of the ureters. Once the urine reaches the bladder, it can be stored until it is ready to be eliminated from the body through the urethra. The heart is not involved in the passage of urine; rather, it pumps blood throughout the body. The bladder serves as a reservoir for urine before it exits via the urethra. Therefore, the correct flow is from the kidneys to the ureters, and understanding this process is essential in both anatomy and physiology.
