Vedclass · Answer

(B) The intestinal mucosa is protected from the highly acidic chyme entering from the stomach primarily by the alkaline secretions.$1$. The pancreas secretes pancreatic juice containing bicarbonate ions $(HCO_3^-)$,which neutralizes the acidic chyme.$2$. Brunner's glands (submucosal glands) present in the duodenum secrete an alkaline,mucus-rich fluid that further neutralizes the acid and protects the intestinal wall.$3$. Goblet cells in the intestinal mucosa secrete mucus,which provides a physical barrier and lubrication for the lining.
