ANATOMY

Detailed explanation-1: -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-2: -Peristalsis: The movement of food in the alimentary canal is mediated by the process called peristalsis. It is a type of involuntary muscular movement that occurs in the digestive system. It begins with the swallowing of food in the mouth and propulsion throughout the gastrointestinal tract.

Detailed explanation-3: -The stomach muscles churn and mix the food with digestive juices that have acids and enzymes. These juices help break up food into much smaller pieces. By the time food is ready to leave the stomach, it has been turned into a thick liquid called chyme (kime).

Detailed explanation-4: -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-5: -Peristalsis is a wave-like motion which brings about the movement of food and liquid through muscle contractions. It is an involuntary action of the muscles and hence cannot be under one’s will. But, the muscles that are involved in peristalsis, the smooth muscles, function when they are triggered to do so.
