Hydrochloric Acid Stomach Concentration Gradient Meaning

Enterogastrones are enterogastric inhibitory hormones liberated from the duodenal mucosa by acid chyme (ie, cholecystokinin: CCK, gastric inhibitory peptide:.

(HCl) in the stomach forms hydrogen (H+) ions and chloride (Cl-) ions.

All the events occur in the "magic" arbitarily defined threshold around pH 4.
