The esophagus (American English) or oesophagus (British English), commonly known as the foodpipe or gullet, is an organ in vertebrates which consists of a fibromuscular tube through which food passes, aided by peristaltic contractions, from the pharynx to the stomach.everal disorders affect the motility of food as it travels down the esophagus. This can cause difficult swallowing, called dysphagia. Achalasia refers to a failure of the lower esophageal sphincter to relax properly, and generally develops later in life.
