Question

why does HCL does not come outside while vomiting? if comes then why oesophagus does not destroyed? ​

Answer 1

Hey, it IS possible for stomach acid to be regurgitated as you regurgitate. The oesophagus is most probably not destroyed due to the mucosal lining..

Hope this helped...

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.
