This document contains numerous unlabeled diagrams and images of gastrointestinal anatomy. It includes sections on the GI tract, vasculature, stomach, pelvis, abdominal wall, and cross sections of the abdomen at various levels. There are also practice questions asking to identify structures, their branches or sections, and relationships between vessels. The document appears to be a review of GI anatomy intended for medical students.
