Quizplus · Accepted Answer

Gastrin is primarily released in response to proteins, alcohol, and caffeine present in the stomach. It stimulates the release of hydrochloric acid and pepsinogen, which aid in the digestion of proteins. Parasympathetic innervation, sight, and smell of food do not directly stimulate gastrin release.
