Explanation:
Detailed explanation-1: -The stomach: At the end of the esophagus is a muscular ring or valve called a sphincter (SFINK-ter). The sphincter lets food enter the stomach, then squeezes shut to keep food and liquids from flowing back up into the esophagus.
Detailed explanation-2: -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: -There is a muscular ring at the point where the esophagus and stomach meet. It is called the lower esophageal sphincter (LES). Normally, this muscle relaxes when you swallow to allow food to pass into the stomach.
