	Absorption definition - Allergies: allergy symptoms, treatment, and medications by MedicineNet.com
		In the intestinal tract, absorption is the uptake of food (or other substances) from the digestive tract.
		In immunology, absorption is the process by which an antibody or antigen is used to remove a corresponding antigen or antibody from a mixture.
		In the body, absorption is the process whereby a cell, tissue or organ takes up a substance.

	digestive tract - Hutchinson encyclopedia article about digestive tract
		It is a complex organ, specifically adapted for digestion and the absorption of food.
		Tube through which food passes in animals – it extends from the mouth to the anus and forms a large part of the digestive system.
		The muscles in the wall of the alimentary canal contract, mixing food with the enzymes and slowly pushing it along in the direction of the anus in a process known as peristalsis.

	Digestive system animation illustrating digestion - Constipation Advice
		The human digestive system, otherwise known as the gut or gastrointestinal tract, is essentially a continuous muscular tube about 7-8 metres long in adults running from the mouth to the anus (back passage).
		This is, in fact, the longest section of the digestive tract and consists of the duodenum, the jejunum and the ileum.
		Otherwise known as the gullet or food pipe, is the first section of the digestive tract which conveys ingested food and drink from the mouth to the stomach.

	Herbsplus4health - The Digestive System
		Digestive tissues maintain the ability to function properly when we obtain sufficient amounts of the antioxidant vitamins and other substances, such as carotenoids (found in fruits, vegetable, grains and cereals).
		The digestive system is the means by which the body transforms food into the energy it needs to build, repair and fuel itself.
		About 90 percent of absorption takes place in the small intestine.

	Digestive System/ Functions of the Digestive System
		Digestion and absorption occur in the digestive tract.
		The digestive system includes the digestive tract and its accessory organs, which process food into molecules that can be absorbed and utilized by the cells of the body.
		This is mechanical digestion, which begins in the mouth with chewing or mastication and continues with churning and mixing actions in the stomach.

	Comparison beweet the digestive tracts of a carnivore,a herbivore and Man
		Digestion of food in a carnivore is performed by enzymes produced by glands in the animal's own body and all the absorption of nutrients in that food is through the wall of the small intestine.
		This, where no further digestive processes occur, does tend to harbour a variety of organisms which form certain vitamins such as pyridoxine, vitamin B-12, biotin, vitamin K and folic acid but, as these are not absorbed through the wall of the colon, they are of little account.
		As all carnivores' digestive systems are the simplest, being essentially a long piece of pipe with a single bulge near the beginning, we will consider the dog first.

	Ultra-Enzyme Support Combines 14 Different Essential Digestive Enzymes
		Where enzymes are not present at the time of food consumption food is not broken down as completely, absorption of nutrients is impaired, a strain is put on the digestive system, immune function is impaired and digestive distress including gas and bloating can occur.
		Digestive enzymes break down food particles so they can be absorbed.
		Enzymes that can break down food are present in all foods including animal products but the heat from cooking and processing kills them and the enzymes our body produces are affected by age.

	Le Magazine, April 1999 - Cover Story: Digestive Enzymes: The Missing Link
		Enzymes are a vital component of the digestive process, essential to the body's absorption and full use of food.
		In pathological digestive diseases, the oral intake of exocrine pancreatic enzymes is of key importance in the treatment of maldigestion in chronic pancreatitis with pancreatic insufficiency, according to Schneider et al.
		Digestive organs such as the pancreas and liver produce most of the body's digestive enzymes, while the remainder should come from uncooked foods such as fresh fruit and vegetables, raw sprouted grains, seeds and nuts, unpasteurized dairy products, and from enzyme supplements.

	Stomach stapling - Wikipedia, the free encyclopedia
		Stomach stapling is more effective when combined with a malabsorptive technique, in which part of the digestive tract is bypassed, reducing the absorption of calories and nutrients.
		The bottom of the pouch is formed from compression of the stomach by a saline-filled band around some of the outside of the stomach.
		In the bottom of the pouch is an approximately 1-cm hole through which the pouch contents can flow into the remainder of the stomach and thence onto the remainder of the gastrointestinal tract.

	Winged Wisdom Pet Bird Magazine - The Avian Digestive Tract - Pet Birds
		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.
		Chemical digestion and absorption of food occurs in the small intestine.

	The Digestive System
		The digestive system carries out six basic processes; ingestion, secretion, propulsion, digestion, absorption and defecation.
		Mechanical digestion is chewing up the food and your stomach and smooth intestine churning the food, while chemical digestion is the work the enzymes do when breaking large carbohydrate, lipid, protein and nucleic acid molecules down into their subcomponents -these and others are the nutrients-.
		There are two basic divisions to the digestive system, these are the gastrointestinal (GI) tract, also known as the alimentary canal, and the accesory digestive organs.

	Digestive Diseases
		Certain digestive diseases such as Crohn's disease, celiac disease (a digestive disease that damages the small intestine and interferes with absorption of nutrients from food) and injuries to the small intestine can also reduce the amount of lactase available to process lactose properly.
		It is caused by a shortage in the body of lactase, an enzyme produced by the small intestine, which is needed to digest lactose.
		Lactose intolerance is the inability to digest lactose, the sugar primarily found in milk and dairy products.

	New Developments in Color Therapy: Acupuncture Meridians Facilitate the Body's Absorption of Light
		Colored light has a particular ability to balance the autonomic nervous system, which is crucial in most chronic and functional disorders as it regulates all of the automatic processes of the human body: breathing, the beating of the heart, the functioning of the digestive tract, the stress response.
		So the light emitted from a full spectrum fluorescent bulb would be different in nature from the full spectrum light emitted by one of the noble plasma gases, as it is in the case of the Photon Stimulator, and certainly different from that emitted by an incandescent bulb.
		Light from the hypothalamus is then sent to the pineal gland, the body's light meter and only gland in the body not controlled by higher neurological centers.

	The Enteric Nervous System
		The nervous system exerts a profound influence on all digestive processes, namely motility, ion transport associated with secretion and absorption, and gastrointestinal blood flow.
		Connection to the central nervous system also means that signals from outside of the digestive system can be relayed to the digestive system: for instance, the sight of appealing food stimulates secretion in the stomach.
		The principal components of the enteric nervous system are two networks or plexuses of neurons, both of which are embedded in the wall of the digestive tract and extend from esophagus to anus:

	Digestion Health
		The pancreas produces three important digestive enzymes: amylase, which helps digests starch; lipase, which takes part in the absorption of fat; and protease, which breaks down protein.
		Although both kinds can be found throughout the digestive tract, acidophilus generally thrives in the small intestine and bifdobacteria in the juncture of the intestines and in the large intestine.
		"We see symptom changes in one week or two." Since herbs are taken orally and work directly on the digestive system, "they are often the treatment of choice for GI (gastrointestinal) problems," he continues.

		If this digestive function is not performed efficiently, incompletely digested protein fragments may be absorbed into the bloodstream.
		Carminatives (also called aromatic digestive tonics or aromatic bitters) may be used to relieve symptoms of indigestion, particularly when there is excessive gas.
		Three major categories of herbs are used to treat indigestion when no cause for the condition is known: bitters (digestive stimulants), carminatives (gas-relieving herbs), and demulcents (soothing herbs).
