Detailed explanation-1: -The esophagus is a hollow, muscular tube that connects the throat to the stomach. It lies behind the trachea (windpipe) and in front of the spine. In adults, the esophagus is usually between 10 and 13 inches (25 to 33 centimeters [cm]) long and is about ¾ of an inch (2cm) across at its smallest point.

Detailed explanation-2: -Lower thoracic: from midway between tracheal bifurcation and gastroesophageal junction to GE junction, including abdominal esophagus; 32-40 cm.

Detailed explanation-3: -The esophagus is a 25-cm long muscular tube that connects the pharynx to the stomach. The length of the esophagus at birth varies between 8 and 10 cm and measures about 19 cm at age 15 years.

Detailed explanation-4: -The midthoracic esophagus includes the proximal half of the esophagus from the tracheal bifurcation to the esophagogastric junction (24–32 cm from the gums).

Detailed explanation-5: -The gastroesophageal (GE) junction is located 38 to 40 cm from the incisors and is easily recognized. A more proximal location of the junction suggests a hiatal hernia or Barrett’s esophagus.
