Accessory Organs of Digestion
Strictly speaking, the liver, gallbladder, and pancreas are not organs of digestion. But the roles they play in cleansing the body of toxins and producing essential hormones and enzymes that aid in digestion make them worthy of discussion. This module considers these organs, emphasizing their role in digestion.
An Introduction to Digestive System Disorders
This module presents an overview of the various categories of digestive system disorders. It provides a useful context for understanding where your products fit into the range of conditions that can affect the digestive system.
Gastric, Duodenal, and Stress Ulcers
This module focuses on peptic ulcers, which are technically associated with acid and pepsin. They require the acid environment that exists in the stomach (gastric ulcer) and duodenum. The module distinguishes these from stress ulcers, and explores further the cause, symptoms, diagnosis, and treatment of peptic ulcers.
Gastroesophageal Reflux Disease (GERD)
This module looks at the etiology, symptoms, diagnosis, and treatment of GERD.
Inflammatory Bowel Disease–Crohn’s Disease and Ulcerative Colitis
This module discusses two chronic inflammatory diseases of the bowel--Crohn's disease and ulcerative colitis. They are commonly referred to as inflammatory bowel disease (IBD).
Irritable Bowel Syndrome (IBS)
This module looks at the etiology, symptoms, diagnosis, and treatment of irritable bowel syndrome (IBS).
Overview of the Digestive System
This module introduces you to the functions of the digestive system, the organs that connect to form the gastrointestinal (GI) tract, and the tissues that comprise the GI tract. It also acquaints you with the structure that helps keep the organs in place--the peritoneum.
Structures that Begin the Digestive Process
This module discusses the components involved in the initial steps of digestion. These include structures within the mouth (oral cavity) and two organs (the pharynx and esophagus), which move food from the mouth to the stomach and intestines.
The Physiology of Digestion and Absorption
The process of digestion includes all the changes food undergoes in the alimentary canal so nutrients can be absorbed. Some of the changes are mechanical, and others are chemical. This module discusses these digestive processes and the mechanisms by which various substances are absorbed.
The Stomach, Intestines, and Appendix
The processes of digestion and absorption occur mostly in the stomach and small and large intestines. This module explores these organs and their functions. It also addresses the significance of the appendix.
