Gastrointestinal Tract Is Organ System That Enables Us To Ingest Food Via Mouth, Digest It By Breaking It Down, Absorb It, And Then Expel Remaining Waste As Faeces Via Anus. Gastrointestinal Tract Is Made Up Of Series Of Hollow Organs Joined Together In Long Tube With Many Folds From Mouth To Anus. Hollow organs that make up gastrointestinal tract include mouth, oesophagus, stomach, small intestine, cecum, colon, rectum and anal canal. Organs of gastrointestinal tract contain layers of muscles, enabling their walls to move food through tract by process called peristalsis, allowing for breaking down and absorption of food to take place. Oesophagus Is Muscular Tube, Transports Food And Liquid From Pharynx To Stomach. It descends down into thorax and enters abdomen, where it then joins stomach. Stomach Is Located Between Oesophagus And Duodenum. After food enters stomach, muscular walls of stomach act to mix food and liquid with digestive juices. Contents of stomach, call chyme, are then empty into small intestine. Small Intestine Is Approximately 6. 5m long and extends from stomach to large intestine. Anatomically, small intestine can be divided into three parts: jejunum and ileum. Appendix Is Small, Blind-end Tube That Is Attached To Cecum. It contains large amounts of lymphoid tissue, and is not thought to any vital functions. Cecum Is First Part Of Large Intestine And Is Located Between Ileum And Ascending Colon. It acts as store for chyme, which it receives from ileum. Colon extends from cecum to anal canal, and be divided into four parts anatomically. It receives digest food from intestine, and absorbs water and electrolytes to form faeces. Rectum Is Located Between Large Intestine And Anal Canal, And Enables Temporary Store Of Faeces. Anal canal is final segment of gastrointestinal tract, and is involved in defecation and maintaining faecal continence. In this section, learn more about anatomy of gastrointestinal tract-oesophagus, stomach, small intestine, appendix, cecum, colon, rectum and anal canal.

Introduction to the gastrointestinal system

Gastrointestinal Tract Consists Of Hollow Muscular Tube Starting From Oral Cavity, Where Food Enters Mouth, Continuing Through Pharynx, Oesophagus, Stomach And Intestines To Rectum And Anus, Where Food Is Expel. There are various accessory organs that assist tract by secreting enzymes to help down food into its component nutrients. Thus, salivary glands, liver, pancreas and gall bladder have important functions in digestive system. Food is propelled along length of GIT by peristaltic movements of muscular walls. Primary Purpose Of Gastrointestinal Tract Is To Break Food Down Into Nutrients, Which Can Be Absorbed Into Body To Provide Energy. First, food be ingest into mouth to be mechanically processed and moisten. Secondly, digestion occurs mainly in stomach and small intestine where proteins, fats and carbohydrates are chemically broken down into their basic building blocks. Smaller molecules are then absorbed across epithelium of small intestine and subsequently enter circulation. Large intestine plays key role in reabsorbing excess water. Finally, undigested material and secrete waste products are excrete from body via defecation. In case of gastrointestinal disease or disorders, these functions of gastrointestinal tract are not achieved successfully. Patients may symptoms of nausea, vomiting, diarrhoea, malabsorption, constipation or obstruction. Gastrointestinal problems are very common and most people will have experienced some of above symptoms several times throughout their lives.

Anatomy of the Digestive System

Extending from mouth to anus, digestive tract is one of largest systems in human body. It contains organs that regulate food intake, its digestion absorbtion of useful materia that it contain. In addition this, digestive system also eliminates waste products from food and products from various endogenous metabolic processes. In nutshell, digestive tract have tumultuous responsibility of converting large chunks of food into their constituent micro-molecules that will subsequently be used to build and repair body. This article will discuss anatomy of digestive system. Digestive System Can Be Broken Down Into Two Major Components: There Is Primary Digestive Tract, Which Functions Mainly As Conduit And Storage Pathway. This portion is needed in order to move food contents along tract so that absorption of nutrients and excretion of undigested substances can occur. Tract also allow for of food at different stages of digestion. This is important because some enzymes produced in one part of tract will not function optimally in another part of tract. Another Component Is Accessory Digestive Tract. This group of organs are responsible for and secretion of enzymes to facilitate chemical digestion. This article aims to give overview of anatomy and function of digestive tract. Details regarding neurovascular supply, histology, and clinically significant points each segment of digestive tract can be found in respective articles. It will also briefly mention few elements of abdominal examination.
