This document summarizes the development of the gastrointestinal tract in a human embryo. It describes how the foregut, midgut, and hindgut develop from the endoderm and form different parts of the GI tract. It also explains the rotation of the midgut loop during development and how this establishes the positions of structures like the cecum, appendix, and ascending colon. Finally, it briefly mentions some potential anomalies that can occur during gastrointestinal development.
