Making the world better, one answer at a time. The urinary bladder and ureters are lined with transitional epithelium. This tissue allows the bladder to stretch when full and contract when empty. It looks like cuboidal epithelium when the bladder is contracted, and like stratified epithelium when distended.
Urine leaves the bladder through a tube-like structure called the urethra. The lining of the urethra is epithelium.The wall of the urethra is smooth muscle. Urine flow is controlled by two uretheral sphincters: the internal urethral sphincter and the external urethral sphincter. The internal urethral sphincter is at the start of the urethra. This sphincter is composed of smooth muscle.he lining of the urethra is epithelium. The wall of the urethra is smooth muscle.
