a) Hydrochloric acid that is released from your stomach is strong enough to burn your skin, but it can’t harm your stomach because of a protective mucous lining of stomach wall. But this mucous lining is not present in the intestine. So what happened with the acidic food when it enters into the small intestine from stomach? Will it harm the intestinal lining or not? Justify your answer.

Explanation:
Second, HCl in the lumen doesnt digest the mucosa because goblet cells in the mucosa secrete large quantities of protective mucus that line the mucosal surface. Basic electrolytes, such as HCO3-, trapped inside the layer of mucus neutralize any HCl that penetrates the mucus
