ANATOMY

Detailed explanation-1: -The tube that carries urine from the kidney to the bladder.

Detailed explanation-2: -Ureters. The ureters are tubular in structure about 22–30 cm in length and connect the renal pelvis to the bladder. It is along this route that the ureters transport urine from the site of manufacture in the kidneys to the bladder for storage prior to voiding.

Detailed explanation-3: -Two ureters. These narrow tubes carry urine from the kidneys to the bladder. Muscles in the ureter walls continually tighten and relax forcing urine downward, away from the kidneys.

Detailed explanation-4: -Urine drains from the ducts in the papilla into a renal calyx. Each calyx is lined by transitional epithelium, or urothelium. The calyces merge into the renal pelvis. The renal pelvis narrows at the ureteropelvic junction to join the ureter.

Detailed explanation-5: -These tubes are called the ureters. The bladder stores urine until it’s time to urinate. Urine leaves the body through another small tube called the urethra. A ureteral obstruction is a blockage in one or both of the tubes (ureters) that carry urine from the kidneys to the bladder.
