This document provides an overview of the digestive system through multiple sections: 1) An introduction covering the anatomy and histology of the alimentary canal. 2) Sections on the functional anatomy of the upper GI tract, small intestine, and large intestine describing their roles in digestion. 3) A section on chemical digestion and absorption outlining the enzymes and processes involved. The document quizzes the reader with multiple choice questions at the end of each section.
