-
A thin pellucid liquor, separated by a peculiar set of secretories in the mucous membrane of the stomach, which open upon its internal tunic. It is the principal agent in digestion, and contains pepsin as its characteristic compound. In the empty stomach it is neutral, but during digestion it becomes acid, from the separation of free hydrochloric acid.
By Daniel Lyons
-
A fluid, secreted from the mucous membrane of the stomach. As met with, it is a mixture of the fluids secreted by that organ with those of the supra-diaphragmatic portion of the alimentary canal. Owing to such admixture, the most contrary properties have been assigned to it. That such a fluid is secreted, which concurs powerfully in digestion, is evident from many considerations, and has been positively proved by the author and numerous others. It was found by him to contain, in man chlorohydric and acetic acids. The gastric fluid in cases of sudden death sometimes corrodes and perforates the stomach; giving rise to interesting questions in medical jurisprudence.

-
Syn.: ferment of stomach. A fluid poured into the stomach by the gastric glands during the process of digestion. It consists of water and salts, pepsin, rennin, and a little free hydrochloric acid. Its principal action is the dissolution of proteids which it changes into the diffusible peptones and proteoses.
