The hormones secretin and cholecystokinin target the pancreases. ---, and, to release juice and bile into the small intestine for digestion

Answer and Explanation:

The endocrine system organizes the secretion of the hormones and the response of numerous glands in the body. The acid environment of the stomach is the essential factor under hormonal control. Gastrin hormone is secreted by G cells in the stomach during the gastric phase. Gastrin encourages the secretion of hydrochloric acid or stomach acid, which helps in protein digestion. When the stomach gets empty, the stomach's acidic environment needed not to be maintained, then a hormone named somatostatin stops the secretion of hydrochloric acid. During the intestinal phase, digestive secretion from the pancreas, gall bladder, and liver helps digest chyme in the duodenum. A hormone called secretin stimulates the pancreas to produce alkaline bicarbonate solution to deactivate the acidic chyme. In tandem, secretin acts with another hormone named cholecystokinin (CCK). CCK encourages the pancreas to release pancreatic juice and encourages the gallbladder to secrete bile into the duodenum.
