Identify the cells whose secretion protects the lining of gastro-intestinal tract from various enzymes.
Goblet cells
Oxyntic cells
Duodenal cells
Chief cells
A.
Goblet cells
Goblet cells secrete mucus and bicarbonates present in the gastric juice which plays an important role in lubrication and protection of the mucosal epithelium from excoriation by the highly concentrated HCl.
