The endodermal diverticulum of the caudal foregut develops into the GB. The GB lies between liver segments 4B and 5 and is supplied by the cystic artery. Cholecystokinin and vagal stimulation result in GB contraction, delivering bile (synthesized in

The rectum develops from endoderm, emerging from the distal tip of the hindgut. The rectum measures 12 to 15 cm. Resting rectal pressure is approximately 10 mm Hg. Internal hemorrhoids cause painless bright-red bleeding. Surgeons evaluate the rectum
