Question

Quizplus · Accepted Answer

The migrating motility complex (MMC) is a type of peristalsis that occurs in the small intestine. It is a cyclic pattern of contractions that begins in the stomach and moves through the small intestine, serving to clean out any remaining food particles and bacteria. Segmentation is another type of movement in the small intestine, but it is characterized by localized contractions that mix the chyme with digestive enzymes. Emulsification refers to the breakdown of fat globules into smaller droplets, which is accomplished through the action of bile. Autoregulation refers to the ability of an organ or tissue to regulate its own blood flow, while mastication refers to the chewing of food in the mouth.
