  chyme - HighBeam Encyclopedia
chyme, semiliquid substance found in the stomach and resulting from the partial digestion of food by the salivary enzyme amylase, the gastric enzyme pepsin, and hydrochloric acid.
The rhythmic muscular action of the stomach wall (peristalsis) moves the chyme into the duodenum, the first section of the small intestine, where it stimulates the release of secretin, a hormone that increases the flow of pancreatic juice as well as bile and intestinal juices.
Chyme also stimulates the release of cholecystokinin, a hormone that primarily increases the flow of bile but also increases the proportion of digestive enzymes in the pancreatic juice.

 Chyme - Encyclopedia, History, Geography and Biography
Chyme slowly passes through the pyloric sphincter and into the duodenum where the extraction of nutrients begins.
Chyme is acidic, as it is a very low pH, around 2, that of the stomach.
To counteract this, the duodenum secretes a hormone which causes the gall bladder to contract, releasing bile (an alkali) into the duodenum, and also for the pancreas to secrete large amounts of sodium bicarbonate, to neutralize the pH to 7 before reaching the ileum.

 What is Chyme?
Chyme is the partially digested mass of food that is forced into the small intestine.
Chyme combined with bile ultimately is secreted from the body in the form of bowel movements.
In these cases, chyme may be improperly formed and not reach the small intestine, or it may leave the small intestine too quickly, before the intestine has time to strip the chyme of its nutrients.

Chyme is the liquid substance found in the stomach before passing the pyloric valve and entering the duodenum.
Chyme slowly passes through the pyloric valve and into the duodenum where the extraction of nutrients begins.
Depending on the quantity and contents of the meal, the stomach will digest the food into chyme anywhere between 40 minutes and a few hours.

 Stomach: Encyclopedia of Nursing & Allied Health
There is a sphincter (circular muscle) between the esophagus and the stomach, which allows food to pass into the stomach and prevents chyme (the semi-fluid mass into which food is converted by gastric enzymes) from flowing backwards into the esophagus.
The pyloric valve is situated between the stomach and the small intestine, which allows chyme to pass into the small intestine and back into the stomach.
The muscles are responsible for mixing the chyme and moving it through the stomach to the small intestine.

 The Dispatch - Serving the Lexington, NC - News
Chyme is the liquid substance found in the stomach before passing through the pyloric valve and entering the duodenum.
With a pH of around 2, chyme emerging from the stomach is very acidic.
As it is protected by a thick layer of mucus and utilises the neutralizing actions of the sodium bicarbonate and bile, the duodenum is not as sensitive to highly acidic chyme as the rest of the small intestine.

Comparison of caecal chyme and faeces of pigs as inoculum for the fermentation of hay, oat bran and gelatine with the modified Hohenheim gas test.
Faecal samples are often used as inoculum for the simulation of fermentation processes in the large intestine of the pig in vitro.
The use of faeces as inoculum requires that the microbial population in the faeces is comparable to the microbial population in the large intestine.

 Ethics @ Brandeis - CHYME
CHYME used oral history and story-telling practices to build capacities for listening, communicating, and understanding among those who work with young people in the Middle East, and in turn, among the youth themselves.
CHYME was a collaboration among four partner institutions: Givat Haviva (Israel), Masar (Jordan), the Palestinian House of Friendship (Palestine), and Brandeis University.
During the CHYME institute, the creation of digital stories provided opportunities for the participants to explore both their commonalties and their differences and to discuss aspects of the Middle East conflict in a mode both creative and personal.

 BIOL 238 Class Notes - Digestive System
Chyme surges forward as a result of muscle contraction but is blocked from entering the duodenum by the pyloric sphincter.
Eventually as the chyme is removed, the pH increases and gastrin and the "go" signal resumes and the process occurs all over again.
These movements cause the chyme to move in several large steps through the colon, stopping at each step to be further concentrated and converted into feces.

 Chyme   (Site not responding. Last check: 2007-10-11)
The food squeezed into the upper portion of the stomach is ground and mixed thoroughly with digestive chemicals into a thick liquid called chyme.
Chyme bears no resemblance to the original food because the starches have been partially split, the proteins have been uncoiled and clipped, and fat has been separated from the mass.
The chyme is squirted forcefully into the top of the small intestine.

 (DIGESTIVE) Small Intestine
In the small intestine, chyme is finally mixed for its passage to cells.
In addition to digesting chyme, the small intestine is responsible for absorbing the processed food into the bloodstream, so that energy can be derived from the food.
The main job of the small intestine is to digest any undigested chyme, and to rid the body of any unneeded wastes by sending it to the anus.

 La Casa De Comida - In the Zoo - The Digestive System - Parts of the Digestive System - Small Intestine
Chyme passes through the small intestine slowly, and so the enzymes have time to act on the food and raise the pH of the acidic chyme.
The chyme is spread over the surface of the small intestine and mixed with digestive fluids by contractions.
Occasionally a stronger wave moves the most liquid of the chyme further down the small intestine, leaving behind the more solid remains to be digested further.

 The Digestive Process   (Site not responding. Last check: 2007-10-11)
After the bolus is swallowed, it enters the esophagus where it continues to be warmed and lubricated as it moves toward the stomach.
The acidic environment of the stomach and the action of gastric enzymes convert the bolus into chyme, a liquefied mass that is squirted from the stomach into the small intestine.
Undigested chyme proceeds from the small intestine into the large intestine (colon), where it becomes concentrated, as liquid is absorbed in preparation for excretion.

 chyme
Chyme resembles a thick creamy fluid and is made up of partly digested food, hydrochloric acid, and a range of enzymes.
The muscular activity of the stomach churns this fluid constantly, continuing the mechanical processes initiated by the mouth.
By the time the chyme leaves the stomach for the duodenum, it is a smooth liquid ready for further digestion and absorption by the small intestine.

 Diagnose-Me: Condition: Poor Small Intestine Health
Lipase, amylase, trypsin, chymotrypsin and sodium bicarbonate are received from the pancreas upon hormonal signals from pancreozymin and other hormones (produced in the small intestine) and neural signals from the vagus nerve.
The small intestine is covered with villi and microvilli, which increase by a factor of 600 the surface area of the intestinal wall exposed to chyme.
As chyme enters the small intestine, its acidity causes secretion of the hormone secretin, which signals the pancreas to secrete alkaline juices to neutralize the chyme.

 GI motility and its control
Peristalsis is used to propel chyme form proximal to distal and consists of co-ordinated contractions with relaxation ahead which moves as a wave pushing the chyme ahead of it.
Segmentation contractions are the most common in the small intestinal and serve to mix the chyme with the various secretions of the intestines, and also to ensure that the chyme comes into the maximum contact with the gut wall so that nutrients can be absorbed.
Segmentation contracts also serve to move chyme along the intestine, and generally unless actively stimulated by a reflex the peristalsis is quite weak.

Food, called chyme as it enters the colon and feces as it exits, is propelled forward by rhythmic contractions of the colon.
If that was all that happened — chyme turning into hard and dry feces — we would only have to worry about constipation (from which millions of Americans suffer).
The muscles that normally propel chyme through the colon and out of the body are less and less able to do their job, increasing the risk of constipation and a host of other ills.

 The Small Intestine
As chyme enters the small intestine, the acidity of it causes secretion of the hormone secretin, which signals the pancreas to secrete alkaline juices to neutralize the chyme.
The chyme also initiates a type of small intestine contraction known as segmentation which helps to mix and chop the chyme and propel it along.
It takes about 2-3 minutes for the chyme to advance 1 inch, and all together food can remain in the small intestine between 3-10 hours normally.
