However, your feedback is important to us. The esophagus is a hollow muscular tube that transports saliva, liquids, and foods from the mouth to the stomach. When the patient is upright, the esophagus is usually between 25 to 30 centimeters in length, while its width averages 1.5 to 2 cm. The muscular layers that form the esophagus are closed tightly at both ends by sphincter muscles, to prevent food or liquids from leaking from the stomach back into the esophagus or mouth. When the patient swallows, the sphincters temporarily relax to allow passage of the food through.
The esophagus is a muscular tube about ten inches (25 cm.) long, extending from the hypopharynx to the stomach. The esophagus lies posterior to the trachea and the heart and passes through the mediastinum and the hiatus, an opening in the diaphragm, in its descent from the thoracic to the abdominal cavity.The esophagus has no serosal layer; tissue around the esophagus is called adventitia.he esophagus lies posterior to the trachea and the heart and passes through the mediastinum and the hiatus, an opening in the diaphragm, in its descent from the thoracic to the abdominal cavity.
