Why is it necessary to maintain the ph level, Biology

Assignment Help:

Q Coming from the acid pH of the stomach which pH level does the chyme find when it enters the duodenum? Why is it necessary to maintain that pH level in the small intestine? What are the organs responsible for that pH level and how is it kept?

Entering the duodenum the chyme meets the pancreatic juice under a pH of approximately 8.5 the neutralization of the chyme acidity is necessary to keep sufficient pH level for the functioning of the digestive enzymes that act in the duodenum without the neutralization of the chyme acidity the mucous membrane of the intestine would be injured.

When stimulated by the chyme acidity the duodenum makes a hormone called as secretin. Secretin stimulates the pancreas to release the pancreatic juice and also the gallbladder to expel bile in the duodenum the pancreatic secretion rich in bicarbonate ions is released in the duodenum and neutralizes the chyme acidity this acidity is also neutralized by the secretion of bile in the duodenal lumen.
