Detailed explanation-1: -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-2: -Waves of muscle contractions called peristalsis (pronounced: per-uh-STALL-sus) force food down through the esophagus to the stomach. A person normally isn’t aware of the movements of the esophagus, stomach, and intestine that take place as food passes through the digestive tract.
Detailed explanation-3: -The esophagus: Food travels down a muscular tube in the chest called the esophagus (ih-SAH-fuh-gus). Waves of muscle contractions called peristalsis (per-uh-STALL-sus) force food down through the esophagus to the stomach.
Detailed explanation-4: -To keep food from coming back up from the stomach, the esophagus has two circular bands of involuntary muscle.
Detailed explanation-5: -Peristalsis Is the Contraction of Muscle Tissue That Helps Move and Break Down Foodstuffs. The walls of the alimentary canal include layers of smooth muscle controlled by the autonomic nervous system.
