It arises at the bifurcation of the trachea, passes in front of the esophagus and enters the hilum of the left lung where it divides into a superior lobe bronchus and an inferior lobe bronchus. It is longer, of narrower caliber, and more nearly-horizontal than the right main bronchus, hence, aspirated objects enter it less frequently. |

| It arises at the bifurcation of the trachea and enters the hilum of the right lung, giving off the superior lobe bronchus and continuing downward to give off the middle and inferior lobe bronchi. It is shorter, of greater caliber, and more nearly-vertical than the left main bronchus, thus, aspirated objects more frequently lodge on the right side |
