(kīm), 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. Secretion of hydrochloric acid by the stomach makes the chyme strongly acidic. 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.



the fluid or semifluid contents of the small intestine in animals and man, consisting of gastric digestive products mixed with bile, the secretions of the pancreas and intestinal glands, desquamated epithelium, and microorganisms. Chyme also contains enzymes of the pancreatic juice, such as proteases, α-amylase, and lipase, as well as intestinal enzymes, such as enterokinase, carbohydrases, peptidases, monoglyceride lipase, and phosphatase. Its composition depends on the food ingested and the secretory activity of the digestive system.

In man, about 400 g of chyme per day pass from the small intestine to the large intestine. The motor activity of the intestine agitates the chyme, thus promoting better digestion and absorption of food substances. Specially prepared chyme has therapeutic properties: it is used in certain digestive disorders and metabolic disturbances in agricultural animals.

It is true, that by the agency of gastric juice on food out of the body, a change very similar to chymification can be effected on it; but when we remember that chyme, or the result of real digestion, is essentially the same in its elementary or component principles, whatever be the kind of food from which it is formed, and that as yet we are acquainted with no purely chymical agent which, applied to different substances, gives rise to the same uniform product, we shall be more willing to believe that chymification is neither a purely mechanical nor a purely chymical operation; but the result of a vital process, to which both mechanical and chymical forces contribute, and which no action or combination of inanimate matter can either exactly imitate or supersede.
