Name 4 hormones that regulate the digestion.
Gastrin
Secretin
Cholecystokinin (CCK)
gastric inhibitory peptide (GIP)
Where is Gastrin found in the digestive system?
Gastrin is located in the pyloric areas of stomach and upper duodenum area.
What stimulates Gastrin?
Food in the stomach
nerve input sphincter
slows gastric emptying
What action does Gastrin prompt?
Stimulates the flow of stomach enzymes and acid; stimulates action of lower esophageal
Where is gastric inhibitory peptide (GIP) found?
Duodenum and Jejunum
What stimulates gastric inhibitory peptide (GIP)?
lipids; proteins
What action does Gastric Inhibitory Peptide (GIP) prompt?
Inhibits secretion of stomach aid and enzymes ; slows gastric emptying.
Where is Secretin found?
Duodenum and Jejunum
What stimulates Secretin?
Acid chyme, peptones
What action does secretin prompt?
Secretion of bicarbonate rich pancreatic fluid and slows gastric emptying
Where is cholecystokinin (CCK) found?
Duedenum
What stimulates cholecystokinin (CCK)?
lipids and proteins in the duodenum
What action does cholecystokinin ( CCK) prompt?
Contraction of the gallbladder and flow of bile to duodenum
cause secretion of enzyme rich pancreatic juice and bicarbonate rich pancreatic fluid; slows gastric emptying
