Sustaining pH level in small intestine
Coming from the acid pH of stomach that pH level does the chyme find whenever it enters the duodenum? Why is it essential to sustain the pH level in small intestine? Name the organs accountable for that pH level and how is it reserved?
Expert
Entering the duodenum, the chyme meets the pancreatic juice beneath a pH of around 8.5. The neutralization of the chyme acidity is essential to keep sufficient pH level for the execution of the digestive enzymes which act in the duodenum. Devoid of neutralization of the chyme acidity the mucous membrane of the intestine would be hurt.
Whenever stimulated by the chyme acidity, the duodenum forms a hormone termed as secretin. Secretin stimulates the pancreas to discharge the pancreatic juice and as well the gallbladder to expel bile in the duodenum. The pancreatic secretion, which is rich in bicarbonate ions, is discharged in the duodenum and neutralizes the chyme acidity; this acidity is as well neutralized via secretion of bile in the duodenal lumen.
