	Gastrointestinal tract - Wikipedia, the free encyclopedia (Site not responding. Last check: 2007-11-07)
		Digestion is regulated both hormonally and by the autonomic nervous system:
		These hormones, such as secretin, gastrin and cholecystokinin, are released into the blood by the digestive tract and stimulate digestive juices and cause organ movement.
		The two arms of the autonomic nervous system both influence the digestive process; parasympathetic nerves stimulate secretions and peristalsis while the sympathetic influence is more inhibitory.

	Digestive System
		The smooth muscle in the walls of the tube-shaped digestive organs rhythmically and efficiently moves the food through the system, where it is broken down into tiny absorbable atoms and molecules.
		The alimentary canal (also called the digestive tract) is the long tube of organs - including the esophagus, stomach, and intestines - that runs from the mouth to the anus.
		Celiac disease is a disorder in which a person's digestive system is damaged by the response of the immune system to a protein called gluten, which is found in wheat, rye, and barley and in a wide range of foods from breakfast cereal to pizza crust.

		The digestive system is responsible for the digestion, absorption, and assimilation of fluids, macro- and micro-nutrients (vitamins and minerals) and the elimination of waste from the gastrointestinal tract.
		The digestive system is a series of hollow organs joined in a long, twisting tube from the mouth to the anus.
		The Digestive system plays a very important role in the functioning of the human body in that it regulates the energy break down for the cells of the body.

		The digestive tract is the part of the body in charge of getting nutrients and liquids into the body and for purifying some of the toxins that are introduced.
		Components of the digestive tract range from the teeth, to the pharynx, to the digestive tract to the liver.
		The alimentary canal is the name given to the digestive tract posterior of the pharynx and it includes the esophagus, the stomach, and the intestines which are normally broken up into a large and small intestine based on the width of the tubes.

	Gas in the Digestive Tract (Site not responding. Last check: 2007-11-07)
		Gas in the digestive tract (that is, the esophagus, stomach, small intestine, and large intestine) comes from two sources:
		The body does not digest and absorb some carbohydrates (the sugar, starches, and fiber found in many foods) in the small intestine because of a shortage or absence of certain enzymes.
		Digestive enzymes, such as lactase supplements, actually help digest carbohydrates and may allow people to eat foods that normally cause gas.

		Digestive tract: The canal from mouth through stomach and intestines to the anus
		Introduction: The digestive tract or "gastrointestinal tract" is the long passage that takes food from the mouth all the way through with wastes coming out of the anus.
		The muscular process that moves food through the digestive tract is called peristalsis.

		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.
		Fats: Fat molecules are a rich source of energy for the body.
		Water and salt: Most of the material absorbed from the cavity of the small intestine is water in which salt is dissolved.

		Although digestive enzymes are produced by the pancreas, the tips of the villi in the small intestine also contain digestive enzymes.
		The secretion of digestive enzymes and the types of enzymes secreted by the young pig are dependent upon the age, weight, and diet fed to the pig.
		Because of the digestive enzyme transition that the pig goes through from birth to eight weeks of age, the changing morphology of the intestinal villi, and the necessity of initially using specialized feed sources during the early phases postweaning, a phase-feeding program is highly recommended during the entire starter period.

		Digestion in birds involves a lot of organs, each performing a specific function.
		Hydrochloric acid, mucus and a digestive enzyme, pepsin, are secreted by specialized cells in the proventriculus where chemical digestion begins.
		In addition, a process known as "cloacal drinking" occurs in altricial birds by which microflora are "sucked" into the vent from the nest to colonize the posterior digestive tract.

		The gastrointestinal or digestive tract, also referred to as the GI tract or the alimentary canal or the gut, is the system of organs within multicellular animals which ingests, digests, and egests food, and in the process, extracts energy and nutrients.
		Starch is digested in two steps: First, an enzyme in the saliva and pancreatic juice breaks the starch into molecules called maltose; then an enzyme in the lining of the small intestine (maltase) splits the maltose into glucose molecules that can be absorbed into the blood.
		Musicians used to use strings made of animal gut, now they use strings made of nylon, silk or steel.

		Gas in the digestive tract is not a subject that most people like to talk about, but the truth is that all of us have it and must get rid of it in some way.
		A common cause of excess lower intestinal gas is that a person’s body may not have enough lactase, an enzyme normally found in the small intestine.
		Simethicone, activated charcoal, and digestive enzymes, such as the lactose supplement lactase, are among those doctors often recommend.

	Gas in the Digestive Tract - Digestive Disorders
		Some carbohydrates (sugar, starches, and fiber) are not digested or absorbed in the small intestine because of a shortage or absence of certain enzymes.
		This process produces hydrogen, carbon dioxide, and, in about one-third of all people, methane gases, which are released through the rectum.
		According to the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK), most foods that contain carbohydrates can cause gas, and fats and proteins cause little gas.
