ANATOMY

Detailed explanation-1: -Esophagus: The esophagus is a muscular tube that connects the pharynx (throat) to the stomach. The esophagus contracts as it moves food into the stomach. A “valve” called the lower esophageal sphincter (LES) is located just before the opening to the stomach.

Detailed explanation-2: -What does the esophagus do? The primary function of your esophagus is to carry food and liquid from your mouth to your stomach. When you swallow, food and liquid first move from your mouth to your throat (pharynx).

Detailed explanation-3: -From the throat, food travels down a muscular tube in the chest called the esophagus (pronounced: ih-SAH-fuh-gus). Waves of muscle contractions called peristalsis (pronounced: per-uh-STALL-sus) force food down through the esophagus to the stomach.
