Hormones of Gastrointestinal Tract:

  • The cells of the mucosa in the stomach and intestine release some important hormones as follows:
    • Gastrin: It is secreted by gastric cells of the stomach. It stimulates gastric glands to secrete and release the gastric juice. It also stimulates gastric motility.
    • Enterogastrone or Gastric Inhibitory Peptide: It is se­creted by the duodenal epithelium. It inhibits gastric secretion and motility. It slows gastric contrac­tion.
    • Secretin: It is secreted by the epithelium of the duodenum. It releases bicarbon­ates in the pancreatic juice. It increases the secretion of bile.
    • Cholecystokinin: This hormone is secreted by the epithelium of the entire small intestine. It stimulates the gallbladder to release bile and pancreas to secrete and release digestive enzymes in the pancreatic juice.

Therefore, Cholecystokinin is secreted by the epithelium of the entire small intestine. It stimulates the gallbladder to release bile and pancreas to secrete and release digestive enzymes in the pancreatic juice.
