Explain the Ureters

Ureters, are the two tubes which convey the urine from the kidneys to the urinary bladder. Each tube measures approximately 10 to 12 inches in length. They start from the pelvis of the kidney and pass downwards. What is the structure of the ureters? The outer coat of the ureter consists of fibrous tissue. The middle layer is a muscle layer consisting of smooth muscle (outer longitudinal and inner circular). The inner lining is a mucous membrane consisting of transitional epithelium.

What is the main function of the ureters? The ureters propel the urine from the kidney into the bladder by contraction of the muscle layer. On the other hand, as the urinary bladder contracts, the walls of the ureters are pressed together. This prevents the urine to be forced back to the ureter. So by the simple contractioil of the muscle, the urine is passed from the ureter to the urinary bladder.
