Acid indigestion/heartburn. Acid indigestion (discomfort in stomach) and heartburn (acid rising into . oesaphagus. ) are conditions which arise when excess hydrochloric acid is produced by the gastric glands in the walls of the stomach. The acid, which creates an acidic environment of pH 0.3 to 1.2 is needed to. (maybe… but Probably not. We’re all going to fail).. . By: Madeline Doolin, Bailey Hiles & Adrian Burrus. The Problems. -The stomach maintains a pH of 1-2 due to the secretion of hydrochloric acid by parietal cells in the stomach wall. The extreme acidic environment allows all enzymes to function properly, digesting food and eliminating bacteria.. D4 . pH regulation of . the stomach.
