Achlorhydria is defined as the absence of hydrochloric acid from which digestive fluid?

Explanation:
Achlorhydria means the stomach’s digestive fluid lacks hydrochloric acid. The acid is normally present in gastric juice, produced by parietal cells in the stomach lining, creating a highly acidic environment that helps activate enzymes like pepsin and kill ingested microbes. Bile, pancreatic secretions, and saliva are different fluids with their own roles and components; bile emulsifies fats, pancreatic juice provides enzymes and bicarbonate, and saliva contains enzymes like amylase and mucus, not hydrochloric acid. Therefore, the absence of HCl specifically refers to gastric juice.
