The right upper quadrant (RUQ in the illustration) contains very significant organs, or at least portions of them. Within this quadrant you'll find the right portion of the liver, the gallbladder, right kidney, a small section of the stomach, part of the colon, and sections of small intestine.
Retroperitoneal structures include the rest of the duodenum, the ascending colon, the descending colon, the middle third of the rectum, and the remainder of the pancreas. Other organs located in the retroperitoneal space are the kidneys, adrenal glands, proximal ureters, and renal vessels. Organs located below the peritoneum in the subperitoneal space include the lower third of the rectum and the urinary bladder.
