Ureter

The two ureters connect the kidneys to the urinary bladder. They run in the rear abdominal cavity on both sides parallel to the spine and then pass into the pelvis, where they open into the urinary bladder. Embedded in fatty tissue and located next to the bony structures of the spine and pelvis, the ureters are well protected against injury. Urine is transported through the muscular ureteral tube to the bladder in individual portions in a wave-like rhythm.
