It mainly contains digestive enzyme responsible for the chemical digestion of proteins. These glands extend deep to the mucosa of the stomach wall. Gastric juice is a thin, clear, virtually colorless acid fluid secreted by the stomach glands. – Comparison of Key Differences Key TermsĬarbohydrate Digestion, Fat Digestion, Gastric Juice, Pancreas, Pancreatic Juice, Protein Digestion, Stomach
What is the Difference Between Gastric Juice and Pancreatic Juice What are the Similarities Between Gastric Juice and Pancreatic JuiceĤ. – Definition, Components, Type of Digestionģ. The stomach secretes gastric juice while the pancreas secretes pancreatic juice to the jejunum of the small intestine. Gastric juice and pancreatic juice are the two main types of secretions in the digestive system, containing digestive enzymes.
Furthermore, gastric juice is acidic while pancreatic juice is alkaline. This may not be the complete list of references from this article.The main difference between gastric juice and pancreatic juice is that the gastric juice mainly contains enzymes for the digestion of proteins whereas the pancreatic juice mainly contains enzymes for the digestion of carbohydrates and fat.

This finding is regarded as evidence against the postulation of Hlava that gastric juice is probably responsible for the occurrence of certain cases of acute hemorrhagic pancreatitis. In animals in which this operative procedure has been carried out, the pancreas has been found to undergo no inflammatory or other degenerative changes.
In addition the work has shown that when the larger pancreatic duct is properly transplanted into the wall of the stomach, it may remain patent for months. The findings then serve not only to corroborate the views of Boldyreff, but also to demonstrate the remarkable compensatory activity of the gastric glands under conditions which entail an unusual quantity of alkali in the stomach. Earlier in the process there is no constant alteration of the acidity level in either direction. From the results of these experiments it appears that the presence of a considerable amount of pancreatic juice in the stomach throughout the period of digestion leads only to a moderate decrease in the acidity level of the ingesta in the later stages of digestion. Animals prepared in this manner served also to furnish additional information regarding the possible relation of the hydrochloric acid of the gastric juice to certain acute inflammatory and chronic sclerotic changes in the pancreas. Specimens of test meal for analysis were withdrawn through gastric fistulas made after the method of Janeway. The influx of alkaline fluid was provided for by transplanting the larger pancreatic duct into the wall of the stomach after ligating and dividing the lesser duct. There is but little evidence, however, to indicate whether the acidity level will be depressed temporarily or permanently (hypoacidity) when alkaline material, in considerable amounts, continues to enter the stomach. Numerous studies have shown that any serious interference with the process of regurgitation leads to a rise in the acidity level of the stomach i.e., to a state of hyperacidity. The experiments reported in this paper were carried out for the purpose of ascertaining how the stomach would react, in as far as the secretion of hydrochloric acid is concerned, to a more or less continuous influx of relatively strong alkaline fluid, prolonged throughout the cycle of digestion. The introduction of acid fluid has led to a regurgitation of alkaline duodenal contents, whereas the introduction of alkaline solutions has called forth a secretion of acid gastric juice. The mechanism described for maintaining the optimum level of gastric acidity is designated by Boldyreff as the "self regulation of the acidity of the contents of the stomach." In support of Boldyreff's hypothesis is the evidence obtained from many experiments carried out both on man and on animals, in which solutions of alkali and acid have been placed in the stomach.
