Identify the cells whose secretion protects the lining of gastro-intestinal tract from various enzymes.

  1. Oxyntic Cells
  2. Duodenal Cells
  3. Chief Cells
  4. Goblet Cells

Answer

(4) Goblet Cells

Solution

As per NCERT, the mucosal epithelium of the alimentary canal has goblet cells which secrete mucus.

The mucus (along with bicarbonates) lubricates and protects the mucosal epithelium from excoriation by the highly concentrated hydrochloric acid and digestive enzymes.

Oxyntic cells secrete HCl and intrinsic factor; chief (peptic) cells secrete pepsinogen.
