What structure connects the kidneys to the bladder?

The structure that connects the kidneys to the bladder is the ureters. Each kidney has a ureter that carries urine from the kidney, where it is produced, to the bladder, where it is stored before being excreted. This function is essential for the urinary system, as it facilitates the movement of urine following its formation in the kidneys.

The ureters are muscular tubes that use peristalsis, a wave-like motion, to propel the urine downwards to the bladder. Understanding this connection is important for grasping how the urinary system functions as a whole, including the roles of the kidneys, bladder, and the process of urine transport.
