Ureter

The two ureters are the connection from the kidneys to the bladder. They run in the posterior abdominal cavity on both sides parallel to the spine and then move into the pelvis, where they join the urinary bladder. Because they are embedded in fatty tissue and located next to the bony structures of the spine and pelvis, the ureters are well protected from injury. Urine is transported through the muscular ureteral tube to the bladder in individual portions in a wave-like rhythm.
