Question

Quizplus · Accepted Answer

Peristalsis in the stomach helps to mix food with acid and pepsin, breaking it down further for digestion. Mechanical breakdown of food occurs primarily in the mouth through chewing and in the small intestine through segmentation. The movement of food from the mouth to the stomach is due to swallowing, not peristalsis. The secretion of pepsin also helps to break down proteins, but peristalsis does not directly contribute to this process.
