Gastric Secretion Phases: Understanding Cephalic, Gastric & Intestinal Phases

The phases of gastric secretion are:

Cephalic phase: This phase is triggered by the thought, sight, or smell of food. It is mediated by the vagus nerve and results in the release of gastric juice.

Gastric phase: This phase is triggered by the presence of food in the stomach. It is mediated by the gastrin hormone and results in the release of gastric juice.

Intestinal phase: This phase is triggered by the presence of food in the intestine. It is mediated by the entero-gastric reflex and results in the inhibition of gastric secretion.

Therefore, the correct answer is (d) None of the above.
