	Chapter 21: The esophagus, trachea and main bronchi
		In esophagoscopy, measurements are taken from the upper incisor teeth to indicate the beginning of the esophagus (18 cm), the point at which it is crossed by the left bronchus (28 cm), and its termination (43 cm).
		The right main bronchus may be considered as having (1) an upper (eparterial) part, from which the segmental bronchi for the upper lobe arise, and (2) a lower part, from which the segmental bronchi for the middle and lower lobes emerge (fig.
		Note the vertical folds of the mucosa and the indentations produced by the arch of the aorta (upper white arrow) and by the left main bronchus (lower white arrow).

	Bronchus Summary
		The left principal bronchus divides into the left superior principal bronchus and the left inferior lobe bronchus.
		A bronchus (plural bronchi, adjective bronchial) is a caliber of airway in the respiratory tract that conducts air into the lungs.
		While the left mainstem bronchus departs from the trachea at an angle, the right mainstem bronchus is almost a vertical continuation of the trachea.
