The bronchi tree is a constituent of the trachea. The trachea divides into two main bronchi: one for the left lung and the other for the right lung. The right bronchus is larger than the left bronchus. The bronchi tree forms a more branched tracheobronchial tree.
The primary bronchus then divides into a secondary lobar bronchi. This has three branches on the right and two branches on left. The secondary bronchi then further divide into tertiary bronchi that "supply the bronchopulmonary segments". After the tertiary bronchi, there is a conducting bronchiole and then terminal bronchioles[1]. Bronchiole passageways then evolve into alveoli, which is the site of oxygen and carbon dioxide exchange in the respiratory system.
