Vedclass · Answer

(A) Gastrectomy is the surgical removal of the stomach or a portion of it.The stomach secretes $HCl$ (hydrochloric acid) from the oxyntic (parietal) cells.$HCl$ is essential for the conversion of ferric ions $(Fe^{3+})$ into ferrous ions $(Fe^{2+})$,which are the absorbable form of iron in the small intestine.Without the stomach,the production of $HCl$ is significantly reduced or absent,leading to impaired iron absorption and subsequent iron deficiency anaemia.Therefore,both the Assertion and the Reason are correct,and the Reason provides the correct explanation for the Assertion.

$A$: Gastrectomy causes iron deficiency anaemia.
$R$: Hydrochloric acid secreted by oxyntic cells converts ferric into ferrous and iron is absorbed as ferrous ions.
