Question

The epithelial cells lining the stomach of vertebrates are protected from damage by HCl because (A) HCl is too dilute (B) the epinthelial cells are resistant to the action of HCl (C) HCl is neutralised in the stomach (D) the epithelial cells are covered by a mucus secretion

Tardigrade Admin · Accepted Answer

The epithelium of gastric glands (present in stomach) consists of goblet cells that secrete mucus. Mucus forms a coating on the epithelial lining of the stomach and thus protects it from the action of HCl

Q. The epithelial cells lining the stomach of vertebrates are protected from damage by $H Cl$ because

$H Cl$ is too dilute

the epinthelial cells are resistant to the action of $H Cl$

$H Cl$ is neutralised in the stomach

the epithelial cells are covered by a mucus secretion
