It is the process of breaking down food into smaller particles.
The organs involved in digestion comprise the digestive system.
Various hormones play an important role in digestion.
Of these, the important ones are gastrin, cholecystokinin (CCK), secretin, somatostatin, ghrelin, bombesin, and gastrin-releasing peptide (GRP).
Gastrin stimulates the secretion of HCl and pepsinogen by gastric glands.
A hormone called somatostatin, which is released when the stomach is emptied, prevents the release of hydrochloric acid since the acidic environment does not need to be maintained.
A negative feedback mechanism governs this.
During the intestinal phase of the chyme, Secretin, a hormone, causes the pancreas to create alkaline bicarbonate solution and transfer it to the duodenum in order to neutralise the acidic chyme.
Secretin works in conjunction with the hormone cholecystokinin (CCK).
CCK stimulates the gallbladder to discharge bile into the duodenum in addition to the pancreas to create the necessary pancreatic juices.
