Abdominal aorta and unpaired arteries: celiac trunk will supply foregut, past the duodenum is considered the foregut, superior mesenteric artery will supply the midgut (and rest of the small intestine and large intestine up until splenic flexure) Inferior mesenteric- hingut and the colon and the rectum. Major branches of celiac trunk in the picture: left gastric artery, splenic artery, common hepatic artery. Jejunum and ileum is anchored to the posterior body wall and will not fall out by the mesentery: the mesentery is the anchor of the small intestine. Interperitoneal: organs that are within the abdominal cavity, ex. small intestine.
