Question

Quizplus · Accepted Answer

Inhibition of gastric secretion following a meal involves two mechanisms: the enterogastric reflex and direct inhibition of gastrin release. The enterogastric reflex is initiated by distention of the small intestine and results in inhibition of gastric motility and secretion. The high concentration of H⁺ also directly inhibits the release of gastrin. Therefore, both of these mechanisms are required for inhibition of gastric secretion following a meal. Option D is the only answer option that includes both the enterogastric reflex and direct inhibition of gastrin release.
