Detailed explanation-1: -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.

Detailed explanation-2: -Fibrosis is the growth of excess connective tissue, which causes a mass to form. This often causes compression and blockage of the ureters, which are the tubes that carry urine from your kidneys to your bladder. Tissue masses can block one or both of your ureters.

Detailed explanation-3: -The wall of the ureter has three layers, the adventitia, or outer layer; the intermediate, muscular layer; and the lining, made up of mucous membrane. The adventitia consists of fibroelastic connective tissue that merges with the connective tissue behind the peritoneum.

Detailed explanation-4: -There are no mucosal or submucosal glands, and no submucosa. There is a layer of smooth muscle outside the mucosa: The upper two-thirds has two layers of smooth muscle: inner longitudinally arranged, and outer circularly arranged.

Detailed explanation-5: -Serosa: This thin connective tissue layer covers the bladder dome and is continuous with the peritoneal layer of the abdominal wall. It also contains blood vessels of various sizes. Adventitia: This loose connective tissue layer serves as the bladder’s outer layer in areas of the bladder where there is no serosa.
