Study Notes
Parietal Cells Role
- Parietal cells are responsible for secreting hydrochloric acid (HCl), a key component of gastric juice.
Gastric Analysis and Conditions
- Low basal acid output with positive pentagastrin stimulation suggests Achlorhydria.
- Achlorhydria is the absence of hydrochloric acid in gastric juice.
- Pentagastrin is a synthetic gastrin analog that stimulates gastric acid secretion.
- A positive response to pentagastrin stimulation indicates that the parietal cells are still functional.
- Chromium-51 is a common marker used to assess gastric emptying.
- This is a radioactive isotope that is added to a meal and its passage through the stomach is tracked.
