Stomach is a key organ of our digestive system. It plays a
vital role in proper digestion of food and its transfer from one part of the
system to another. It holds potentially damaging acid inside its cells that, if
accidently leaks out, can cause serious damage to the entire digestive system. It
is mainly concerned with the digestion of all the proteins in our diet. For
this purpose, the acid inside holds key importance to digestion.
