Anatomy and Physiology of the Digestive System

Gastric acid and digestive physiology.

The primary function of the stomach is to prepare food for digestion and absorption by the intestine. Acid production is the unique and central component of the stomach's contribution to the digestive process. Acid bathes the food bolus while stored in the stomach, facilitating digestion. An intact defense against mucosal damage by the stomach's acid is essential to avoid ulceration. This artic...

Ecological physiology of diet and digestive systems.

The morphological and functional design of gastrointestinal tracts of many vertebrates and invertebrates can be explained largely by the interaction between diet chemical constituents and principles of economic design, both of which are embodied in chemical reactor models of gut function. Natural selection seems to have led to the expression of digestive features that approximately match digest...

Effects of Benzimidazole derivatives on digestive system and cardiovascular system

One of the goals of medicinal chemistry research and drug discovery is to provide a rationalbasis for the design of new medicinal agents. Organic compounds and their reactions have beenutilized by people since antiquity. Due to the increasing demand for bioactive molecules, organicchemists are increasingly required to synthesize new compounds of biological interest. AsBenzimidazoles are very us...

The Digestive System

The digestive system is a way for nutrients from the outside environment to get to various parts of the body. At its simplest, the digestive system is a tube running from the mouth to the anus. This tube is similar to an assembly line, or more properly, a disassembly line. Its chief goal is to break down huge macromolecules (proteins,* fats, and starches) that cannot be absorbed as they are int...
