right main bronchusmedical dictionary

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 calibre, and more nearly-vertical than the left main bronchus, thus, aspirated objects more frequently lodge on the right side.

Synonyms: bronchus principalis dexter.
