is essential in the human diet to help exercise the muscles of the digestive tract. An adequate amount of fiber in the diet has been shown to reduce the risks of colon and rectal cancers HOW DOES FIBER WORK ?? Fiber affects the rate of digestion of foods‚ the absorption of nutrients‚ and the movement of waste products (stool) through the colon. It also provides a substrate for beneficial intestinal bacteria. Dietary fiber includes water-soluble and insoluble types‚ which have different

Introduction The Digestive system breaks down the ingested food into absorbable forms of nutrients and absorbs nutrients‚ ions and water from the external environment of the body. It is designed to maximize digestion and absorption. The functional structures of the digestive system are the passage‚ the glands like salivary glands‚ gastric glands‚ pancreatic‚ intestinal glands and liver. Also‚ the four layers of the digestive system are mucosa‚ submucosa‚ muscularis and serosa. The digestive system

THE DIGESTIVE SYSTEM Functions of the Digestive System • Ingestion- where in food from outside of the body enters the alimentary tract through the mouth • Digestion- which could be mechanical (physical breakdown of food into smaller pieces or chemical (enzymatic action) • Absorption of digested materials into venous circulation as well as lymphatic capillaries • Provision of nutrients to the cells of the body • Elimination of undigested materials ANATOMY AND HISTOLOGY OF THE DIGESTIVE

intestinal lining. 2. Protein - Foods such as meat‚ eggs‚ and beans consist of giant molecules of protein that must be digested by enzymes before they can be used to build and repair body tissues. An enzyme in the juice of the stomach starts the digestion of swallowed protein. Then in the small intestine‚ several enzymes from the pancreatic juice and the lining of the intestine complete the breakdown of huge protein molecules into small molecules called amino acids. These small molecules can be absorbed

Bacteria are found in humans from birth‚ where they feed and continue to develop. In the digestive tract they feed from decaying food matter‚ which results in digestion‚ and providing nutrients to the host. Other bacteria host on inanimate objects and decompose things that if left for a while could be unhealthy for a particular environment. The two important chemical processes that are involved in a bacteria cell
