Detailed explanation-1: -The right main bronchus subdivides into three lobar bronchi, while the left main bronchus divides into two. The lobar bronchi (also called secondary bronchi) divide into tertiary bronchi, each of which supplies air to a different bronchopulmonary segment.
Detailed explanation-2: -Bronchopulmonary segment There are 10 bronchopulmonary segments in the right lung (3 in the superior lobe, 2 in the middle lobe, 5 in the inferior lobe), and 8 segments in the left lung (4 in the upper lobe, 4 in the lower lobe).
Detailed explanation-3: -Lobar bronchi are major airways within the respiratory tree that start by division of the principal bronchi on both sides and end at the point of their own subdivision into tertiary or segmental bronchi. Usually, the region that each supplies is divided into a distinct lobe of the lung by the presence of a fissure.
