THORAX ABDOMEN AND PELVIS

Detailed explanation-1: -The ureters are bilateral thin (3 to 4 mm) tubular structures that connect the kidneys to the urinary bladder, transporting urine from the renal pelvis into the bladder. The muscular layers are responsible for the peristaltic activity that the ureter uses to move the urine from the kidneys to the bladder.

Detailed explanation-2: -This mechanism is called the uretero-renal reflex. In the lower part, the ureter obliquely enters the bladder and passes several centimeters beneath the urothelium, so that the intravesical pressure compresses the ureter, preventing the reflux of urine during micturition.

Detailed explanation-3: -Ureteral Peristaltic Activity It is responsible for the transport of a variable volume of urine from the pelvis to the bladder. Normal ureteral function has two separate phases, namely, ureteral filling, which is entirely passive, and ureteral emptying, which is entirely active.
