Explanation / Answer

Digestive enzymes-

Mouth-> lingual lipase- lipid digestion

Salivary amylase-(ptyalin)—- carbohydrate digestion initiation

Stomach -> pepsin —-produced by chief cells — breaks protein in food such as peptides fragments and amino acids

Gastric lipase — produced by gastric chief cells — carbohydrate digestion

HCL— produced by parietal cells— denature the proteins ingested , to destroy any bacteria or virus that remains.

Gastrin — G cells of gastric antrum- actions are gastric secretions, gastric motility , pancreatic secretion

Duodenum—

type I cells and jejunum —Cholecystokinin — pancreatic secretion , gall bladder contraction , small intestine motility , inhibited gastric motility

Secretin- produced by S cells of duodenum — pancreatic secretion, bile secretion , inhibit gastric secretion

Gastric inhibitory polypeptide — duodenum and jejunum— small intestine secretion, and doesnot cause gastric secretion, gastric motility and small intestine motility

Vasoactive intestinal polypeptide (vip) — jejunum — stimulates contractility in the heart , causes vasodiltation , increases glycogenolysis , lowers aterial blood pressure and relaxes the smooth muscle of trachea , stomach and gall blader

Somatostatin — delta cells of islets of langerhans—inhibits insulin and glucagon secretion.
