Question

Which protects the intestinal mucosa from acid as wellas provide an alkaline medium for enzymatic activities?

Answer 1

The mucosa secreted by the goblet cells along with the bicarbonates from the pancreas, protects the intestinal mucosa from acid as-well-as provide an alkaline medium (pH-7.8) for enzymatic activities. Submucosal glands (Brunner's glands) also help in this action.

Answer 2

The mucus protects the intestinal mucosa from acid as well as provide an alkaline medium for enzymatic activities.

• The stomach shields itself from being scorched by the destructive hydrochloric acid, by discharging mucus which is a body fluid that sticks to the stomach dividers.
• Because goblet cells in the mucosa create enormous amounts of protective mucus that line the mucosal surface, the mucus and bicarbonate coat the stomach wall with a protective coating, ensuring that the stomach wall is not harmed by the hydrochloric acid.
