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: -The main function of the esophagus is to propel swallowed food or fluid into the stomach. This occurs through sequential or “peristaltic” contraction of circular muscle in the esophageal body, in concert with appropriately timed relaxation of the upper and lower esophageal sphincters.

Detailed explanation-3: -Peristalsis is the automatic wave-like movement of the muscles that line your gastrointestinal tract. Peristalsis moves food through your digestive system, beginning in your throat when you swallow and continuing through your esophagus, stomach and intestines while you digest.

Detailed explanation-4: -Peristalsis is a series of muscle contractions. These contractions occur in your digestive tract. Peristalsis is also seen in the tubes that connect the kidneys to the bladder. Peristalsis is an automatic and important process.

Detailed explanation-5: -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.
