Right main bronchus - The right main bronchus is shorter and more vertical than the left, approximately 2.5 m (around 1 inch) in length. It divides into smaller bronchi to enter the 3 lobes of the right lung. Left main bronchus - The left bronchus is smaller and longer than the right main bronchus (approximately 5 cm or 1.5 inches.) It, in turn, divides into 2 lobar bronchi which enter the 2 lobes of the left lung.
