- Each bronchus runs freely for a few centimeters, then enters its respective lung. Air flows in and out of each lung through the primary bronchi.
- After entering a lung, each 1 bronchus divides into
secondary (2) bronchi. The secondary bronchi are also known as lobar bronchi because each one directly conducts air to and from one of the lung’s five lobes.
- Within a lobe, tertiary (3) bronchi branch from the secondary bronchi.
- Each 3 bronchus conducts air to and from a bronchopulmonary segment, which is an anatomical and functional subdivision of a lobe.

- Because they conduct air in and out of the bronchopulmary segments, the tertiary bronchi are known as segmental bronchi.
