A

Carina

37
Q

Each main bronchus enters where?

A

42
Q

Segmental bronchi supply the:

A

Bronchopulmonary segments

43
Q

Segmental bronchi give rise to:

A 
Bronchioles
Terminal bronchioles
Respiratory bronchioles
Alveolar sac
Alveoli
44
Q

There are ___ (#) bronchopulmonary segments in each lung

A

10 (though some fuse in the left lung and give 8).
