The ureter is a tube that carries urine from the kidney to the urinary bladder. There are two ureters, one attached to each kidney. ... The ureter is about 10 to 12 inches long in the average adult. The tube has thick walls composed of a fibrous, a muscular, and a mucus coat, which are able to contract.

Explanation:

The wall of the ureter consists of three layers. The outer layer, the fibrous coat, is a supporting layer of fibrous connective tissue. The middle layer, the muscular coat, consists of the inner circular and outer longitudinal smooth muscle. The main function of this layer is peristalsis: to propel the urine.

Answer 2

Answer:

Ureters :

They are a pair of fine whitish distensible muscular tubes of 25-30 cm length, about 3 mm in diameter. Ureters arise from hilum part of the kidneys, descend along the abdominal wall, bend obliquely inwards and upwards to open into the urinary bladder in the region of trigone by oblique slits, one on each side.

Wall of ureter has 3 coats :

external adventitia, middle muscular and inner mucosa. The middle Muscular coat has in itself three layers of smooth muscle fibers - outer longitudinal, middle circular and inner longitudinal layer.

Ureters are always undergoing peristalsis which helps in passing urine from kidney to the urinary bladder.
