Detailed explanation-1: -The muscle movements of peristalsis are often described as wave-like because they contract and relax in a continuous pattern to move food forward. They involve both the circular muscles that ring the tubes of your digestive tract and also longitudinal muscles that span the walls of the tubes.

Detailed explanation-2: -Overview. Peristalsis is a series of wave-like muscle contractions that move food through the digestive tract. It starts in the esophagus where strong wave-like motions of the smooth muscle move balls of swallowed food to the stomach.

Detailed explanation-3: -The type of muscle found in the digestive system is called smooth muscle. Smooth muscle is one of three major types of muscle tissue in the body. It lines hollow internal organs such as the stomach and intestines, as well as blood vessels.

Detailed explanation-4: -Throughout most of the gastrointestinal tract, smooth muscles are organized into two layers of circularly or longitudinally oriented muscle bundles. Smooth muscle cells form electrical and mechanical junctions between cells that facilitate coordination of contractions.
