The esophagus is a muscular tube in vertebrates which food passes from the pharynx to the stomach. The esophagus is continuous with the laryngeal part of the pharynx at the level of the C6 vertebra. Food passes through the esophagus by using the process of peristalsis. The esophagus is lined with mucous membrane and is more deeply lined with muscle that acts with peristaltic action to move swallowed food down to the stomach. The sound we hear when swallowing is the esophagus working.
