Abstract

The gastrointestinal tract is formed during the fourth week of gestation in the form of a small 4 mm hollow tube. The epithelial tissues of the gut are derived from the endodermal layer, whereas the muscles and connective tissues are derived from the mesodermal layer of the embryo during invagination of the embryonic disc. Foregut comprises the esophagus, stomach, duodenum, liver, gallbladder and pancreas. The midgut is composed of jejunum, ileum and the ascending and transverse colon, and the hindgut comprises the descending and rectosigmoid colon.
