The duodenum becomes partly retro-peritoneal, and is fixed by the gastro-hepatic liga ment at the junction of the first and second portions, and by the muscle of Trietz below. The ascending and descending colons lose their mesenteries, becoming partly retroperitoneal, and the hepatic and splenic fiexures become fixed points. The transverse colon alone is allowed to swing free, but here nature has attempted to add additional support to this organ by dropping the omentum from the greater border of the stomach down over the colon and allowing it to fuse with the peritoneum covering it. Another factor of exceedingly great moment is the shape of the abdominal cavity itself, as determined by spine and the bony pelvis. Some writers call attention to the significance of the para-vertebral niches in the maintenance of visceral position. Coffey found that the right kidney actually rests on a four-inch shelf that is heavily padded with fat. The ascending colon lies firmly upon this shelf as well, and is held there by fusion with the parietal peritoneum, and the same is true of the descending colon. Another factor in the maintenance of visceral position is the question of intra-abdominal pressure. The upper organs of the abdominal cavity rest upon the lower ones in a measure as one cushion upon another. The air and liquid contents of the stomach and the bowel exert a hydrostatic pressure which extends in all directions, but owing to the tension of the abdominal walls the reacting force becomes sustaining in character.
