Physiology 214 Human GI System: Comprehensive Summary of Digestion, Anatomy & Regulation

Unlock the complexities of the Human Gastrointestinal (GI) system with this comprehensive summary. Explore the four fundamental processes of digestion—motility, secretion, digestion, and absorption—along with the intricate regulation involving neural and hormonal controls. This document details the anatomical layers of the digestive tract, from the innermost mucosa to the outermost serosa. Dive deep into the specific functions of key organs, including the oral cavity, pharynx, esophagus, stomach, pancreas, liver, small intestine, and large intestine. Understand gastric emptying mechanisms, the role of pancreatic and biliary secretions, and the specialized adaptations for absorption in the small intestine. Ideal for students seeking a thorough understanding of human digestion and physiology.
