Esophagus

Definition

The esophagus is a muscular tube that connects the throat (pharynx) with the stomach, serving as the passageway for food and liquids. It plays a crucial role in the digestive system by propelling swallowed food to the stomach through a series of coordinated muscle contractions known as peristalsis.
