Detailed explanation-1: -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-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: -Upper and lower esophageal sphincters control the movement of food into and out of the esophagus. The lower esophageal sphincter is sometimes called the cardiac sphincter and resides at the esophagogastric junction.
