Physiology of the Gastrointestinal Tract, Sixth Edition, a Two-Volume set, covers the study of the mechanical, physical and biochemical functions of the GI Tract by linking clinical disease and disorder, thus bridging the gap between clinical and laboratory medicine while also covering breakthroughs in gastroenterology, such as the brain-gut axis and microbiome. Additionally, information is provided at the organism level, including animal models of gastrointestinal disorders and therapeutic possibilities. The book covers a wide range of conditions, from food allergies, constipation, chronic liver disease and IBS, also exploring emerging techniques to diagnose and normalize functions of the GI tract. As a highly referenced book, this is a useful resource for gastroenterologists, physiologists, internists, professional researchers and instructors teaching courses for clinical and research students.
