Explain the Intestinal Phase

Rest 10% of the total gastric secretion is discharged in this phase.

When partially digested contents of the stomach reach the duodenum, presence of certain food substances in the small intestine excites gastric secretion. These are meat extract, alcohol etc. Some substances inhibit gastric secretion. These are alkali and fat. If the intestinal food material contains a considerable amount of fat, a hormone enterogastrone is produced. It inhibits gastric secretion and gastric motility that is why after takim a fatty meal (paranthas) you don't feel hungry for about 3-4 hours again. By slowing down the emptying rate of the stomach the contents in the small intestine are thoroughly mixed with bile and pancreatic juice.
