The esophagus is a vertical, hollow, muscular, collapsible tube. In adults it is approximately 10 inches (25 cm) long, and about one inch in diameter. MATERIALS AND METHODS. The study was conducted for the measurement of esophageal length in 196 persons, 97 males and 99 females, with normal esophagogastric endoscopic findings. The distribution of age was from 16 to 77. The distances from the upper incisors to 5 anatomical levels of esophagus (cricopharyngeus narrowing, aortic narrowing, Cited by: 13.
Jun 25, 2016 · The esophagus starts as a continuation of the pharynx, is normally 20 to 30 cm in length in adults, and terminates at the cardia of the stomach. With the head in its normal anatomic position and the neck in neutral flexion, the transition from pharynx to esophagus begins at the inferior edge of the cricoid cartilage opposite the lower border of the sixth cervical vertebra (Fig. 129-1). Between species the diameter of the bronchi and bronchioles vary greatly. The average length of the adult bronchus is 2.5 cm and its average diameter is 13 mm.
[Measurement of the length of the adult esophagus using a fiberogastroscope: 104 cases]. These measurement were respectively 4.4 cm and 3.0 cm longer than the traditional data (P less than 0.01). The difference in the length of the esophagus may be explained on the basis that measurement by rigid esophagoscope is in a straight line, Cited by: 4. The esophagus bleeds into the stomach, often followed by vomiting blood. Esophageal varices: In people with cirrhosis, veins in the esophagus may become engorged and bulge.
