TY - CHAP M1 - Book, Section TI - THE DIGESTIVE SYSTEM A1 - Jaiswal, Kshama A2 - Janson, Lee W. A2 - Tischler, Marc E. Y1 - 2018 N1 - T2 - The Big Picture: Medical Biochemistry AB - The digestive or gastrointestinal system is roughly defined as the anatomical component from the mouth to the anus, including organs responsible for transit, mechanical breakdown, digestion and absorption of foodstuffs, as well as the efficient elimination of solid waste. Included are the mouth and dentitia, pharynx and esophagus, stomach, small intestine, liver, gall bladder, pancreas, large intestine, rectum, and anus. As with the complex integration and control of metabolism, the digestive system is, itself, under the influence of neurological and hormonal regulation that both activates and inhibits many of its complex actions. Most of these complex actions are, themselves, simple biochemical processes of proteins, carbohydrates, lipids, and nucleosides/nucleotides to include enzyme reactions with associated activating and inhibitory molecules, membrane-spanning protein channels, and pumps all leading to the production and storage of energy and essential building blocks for current or future use.
