Essentials of Digestive Physiology

Essentials of Digestive Physiology provides a clear, comprehensive, and structured understanding of how the human digestive system works — from the ingestion of food to the absorption of nutrients. Covering every major organ and function of the gastrointestinal tract, this book is designed for medical, dental, nursing, physiotherapy, and allied health students who need a reliable and concise guide to GI physiology.

The text explains the phases of digestion, secretions, motility, nutrient handling, and the role of accessory organs such as the liver, pancreas, and biliary system. It also includes detailed coverage of human nutrition, including carbohydrate, lipid, and protein digestion and absorption. With an easy-to-follow structure and clinically relevant explanations, this book serves as both a study companion and a practical reference.
