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 takes in food, digests it to extract energy and nutrients, and expels the remaining waste. The GI tract differs substantially from animal to animal. For instance, some animals have multi-chambered stomachs. Gastrointestinal tract - Basic anatomy. Gastrointestinal tract - The gut. < ...

See: Gastrointestinal tract In humans, digestion begins in the mouth where food is chewed with the teeth. The process stimulates exocrine glands in the mouth to release digestive enzymes such as salivary amylase, which aid in the breakdown of food, particularly carbohydrates. Chewing also causes the release of saliva, which helps condense food into a bolus that can be easily passed through the esophagus to the stomach. In the stomach, food is churned and thoroughly mixed with acid and other digestive enzymes with digestive flui ...

The chocolate digestive is a British delicacy, originally produced by McVitie's in 1925.

Two variations exist, milk chocolate and plain chocolate. Currently, a third limited edition white chocolate has been introduced. The US travel writer Bill Bryson described the chocolate digestive as a British masterpiece. Choco

The vocal tract is that cavity in animals and humans, where sound that is produced at the sound source (larynx in mammals; syrinx in birds) is filtered. In birds it consists of the trachea, the syrinx, the oral cavity, the upper part of the esophagus, and the beak. In mammals it consists of the laryngeal cavity, the pharynx, the oral cavity, and the nasal cavity, and in some nonhuman mammals maybe also the airsacs.

Anaerobic digestion is the breakdown of organic matter by bacteria in the absence of oxygen. Anaerobic digestors use the natural process of anaerobic digestion to treat waste, produce energy or both. Anaerobic digesters have been around for a long time, and they are commonly used for sewage treatment and for managing animal waste. Increasing environmental pressures on waste disposal has increased the use of digestion as a process for reducing waste volumes and generating useful byproducts. It is a fairly simple process that can greatly reduce the amount of organic matter which ...

Vomiting (or emesis) is the forceful expulsion of the contents of one's stomach through the mouth. Although it probably evolved as a mechanism for expelling ingested poisons, vomiting may result from many causes not related to poisoning, ranging from gastritis to brain tumors, or elevated intracranial pressure (ICP). The feeling that one is about to vomit is called nausea. It usually, but not necessarily, precedes vomiting, but it does not always lead to vomiting. Antiemetics are somet ...

Cholecystokinin (CCK, previously pancreozymin) is a peptide hormone of the gastrointestinal system responsible for stimulating the digestion of fat and protein. CCK is secreted by the duodenum, the first segment of the small intestine, and causes the release of digestive enzymes and bile from the pancreas and gall bladder, respectively. It also acts as a hunger suppresant. Recent evidence has suggested it plays a major role in inducing drug tolerance to opioids like morphine and heroin, and is partly responsible for the ...

ADME is an acronym for Absorption, Distribution, Metabolization, and Excretion, and describes the disposition of a pharmaceutical compound within an organism. The four criteria all influence the drug levels and kinetics of drug exposure to the tissues and hence influence the performance of the compound as a drug: Absorption  Before a compound can exert a pharmacological effect in tissues, it has to be taken in to the bloodstream — usually via mucous surfaces like the digestive tract (intestin ...

Borborygmus (plural borborygmi) is the rumbling sound produced by the movement of gas through the intestines. The "rumble" or "growl" sometimes heard from the stomach is a normal part of digestion. It originates in the stomach or upper part of the small intestine as muscles contract to move food and digestive juices down the gastrointestinal tract. Although this muscle contraction happens whether or not food is present, rumbles are more common after the organism has gone several hours without eating. This may be why many ...
