When should I call my child's healthcare provider? The carina is the upward-directed ridge seen internally at the bifurcation and is a landmark during bronchoscopy.

The arch of the aorta is at first anterior to the trachea and then on its left side immediately superior to the left main bronchus. Other close relations include the brachiocephalic and left common carotid arteries.

The trachea is supplied mainly by the inferior thyroid arteries. Its smooth muscle is supplied by parasympathetic and sympathetic fibers, and pain fibers are carried by the vagi. Main bronchi Each main bronchus extends from the tracheal bifurcation to the hilus of the' corresponding lung. 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.

The left main bronchus divides into two lobar bronchi, one each for the upper and lower lobes. The upper lobar bronchus may be considered as having 1 an upper division and 2 a lower, or lingular, division.

The right main bronchus, about 2. Because it is in almost a direct line with the trachea, foreign objects traversing the trachea are more likely to enter the right main bronchus. The left main bronchus, 5 cm or more in length, crosses anterior to the esophagus fig. Both bronchi have cartilaginous rings that are replaced by separated plates at the roots of the lungs.

Saunders Company, Philadelphia, A general reference with an extensive bibliography. Questions What lies anterior to the esophagus in the lower part of the thorax? Dilatation of the left atrium can be detected radiographically because of compression of a barium-coated esophagus. This would be approximately behind the middle of the body of the sternum.

Figure legends Figure The trachea and esophagus in relation to vertebral and sternal levels in a subject in the erect position. Figure The relations of the trachea, bronchi, esophagus, and aorta to one another. In the right anterior oblique view, the right lobar and segmental bronchi are omitted because they are not clearly visible in radiographs of this view. For similar reasons, the left lobar and segmental bronchi are omitted from the left anterior oblique view.

The horizontal line indicates the level of the carina. Figure Oblique R. The esophagus is shown coated with barium. 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. Note also the right and left domes of the diaphragm on the left and right sides of the illustration, respectively and the fluid level in the stomach black arrow.
