Trachea above Bifurcation

Transverse section of the trachea, just above its bifurcation, with a bird’s-eye view of the interior.


If a transverse section be made across the trachea a short distance above its point of bifurcation, and a bird’s-eye view taken of its interior (Fig. 963), the septum placed at the bottom of the trachea and separating the two bronchi will be seen to occupy the left of the median line, and the right bronchus appears to be a more direct continuation of the trachea than the left, so that any solid body dropping into the trachea would naturally be directed toward the right bronchus. This tendency is aided by the larger diameter of the right tube as compared with its fellow. This fact serves to explain why a foreign body in the trachea more frequently falls into the right bronchus.
