NEET PG DENTAL EXAM

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 squeezes your esophageal muscles from top to bottom. This pushes food and liquid along. If you could see peristalsis, it would look like a wave passing down your esophagus. To keep food and liquids moving in the right direction, your digestive tract has special muscles along its course called sphincters.

Detailed explanation-3: -Beginning in the esophagus, food moves smoothly through your entire digestive tract by a process called peristalsis, a coordinated, rhythmic wave of muscular contraction that travels in a single direction. Peristalsis works independently of gravity.
