Introduction

Arises at the bifurcation of the trachea, passes in front of the esophagus & enters the hilum of the left lung.

  • gives off superior & inferior lobe bronchi

The bronchus is longer, of narrow caliber & more nearly horizontal than the right main bronchus, thus aspirated objects enter it less frequently.
