Study Notes

Gastric Secretion and Function

  • The daily volume of gastric secretion is approximately 2-3 liters.
  • The mucosa of the body of the stomach is responsible for iron absorption.
  • The most potent stimulus for acid secretion by the parietal cells is histamine.
  • A gastric residuum volume exceeding 100-120 ml can be caused by gastroparesis or pyloric obstruction.
  • During a gastric function test, the pH of the gastric juice can be examined using a stomach tube.
