Answer:
The esophagus or oesophagus, informally known as the food pipe or gullet, is an organ in vertebrates through which food passes, aided by peristaltic contractions, from the pharynx to the stomach. The esophagus is a fibromuscular tube, about 25 cm long in adults, which travels behind the trachea and heart, passes through the diaphragm and empties into the uppermost region of the stomach. During swallowing, the epiglottis tilts backwards to prevent food from going down the larynx and lungs. The word oesophagus is from Ancient Greek οἰσοφάγος, from οἴσω, future form of φέρω + ἔφαγον.
Anatomy. Every feature of esophageal anatomy reflects its purpose as part of the system that delivers nutrition and liquid through the body.
Function. As the upper portion of the digestive system, the esophagus’s primary role is to carry food and liquid down to the stomach.
