Now another important type of cell that is found in the lining of the stomach are cells known as anterochhromaphin cells or anterochromathin like cells. Our anterochromaphinlike cells are responsible for secreting a type of molecule known as histamine and what histamine does is it also stimulates the parietal cells to release hydrochloric acid. So we see two important components. Two important molecules stimulate parietal cells, so g cells secrete gastroin which stimulates parietal cells and our interchromethanlike cells also secrete a molecule known as histaminene that also stimulates the parietal cells to release our hydrochloric acid. And then the parietal cells, by releasing the hydrochloric acid, basically stimulate the chief cells to release our pipsinogen, which is then transformed into pepsin as a result of that hydrochloric acid as a result of that relatively low PH. So what can we actually conclude about the functionality and the purpose of our stomach?
