Normally, the internal organs in the pelvic cavity, such as the urinary bladder, the ovaries, the uterus, and the large intestine, are separate from each other. As a result, they are able to move or slide as the body moves, and it is possible for a surgeon to reach between two organs, without cutting into them, during abdominal surgery. In this condition, they are attached together by internal scars or adhesions and cannot move freely or be separated without cutting.
