From the kidneys, urine travels down two thin tubes called ureters to the bladder. The ureters are about 8 to 10 inches long. Muscles in the ureter walls constantly tighten and relax to force urine downward away from the kidneys. If urine is allowed to stand still, or back up, a kidney infection can develop.
The Function of the Kidney is to get rid of waste and excess body fluid. Example: The Kidneys job is to keep the flow of urine through tâ¦he Kidney and then back out of the Kidney. The waste moves through the URETER which is the tube that connects the Kidney and the urinary bladder. Urine is formed by the Kidneys.
