|
Lobar bronchi are larger than primary bronchi

|
|
Segmental bronchi feed into lobar bronchi
|
|
|
Tertiary bronchi feed into bronchioles
|
Explanation:
Detailed explanation-1: -The right main bronchus divides into three smaller bronchi, whereas the left main bronchus only divides into two bronchi. These so called secondary bronchi divide further into tertiary bronchi. The tertiary bronchi bring air into compartmentalized sections of the lungs called bronchopulmonary segments.
Detailed explanation-2: -Bronchi contain cartilaginous layer, whereas bronchioles do not. Respiratory function of bronchi is to serve as conductors, whereas that of bronchioles is to serve as conductors as well as the sites of gas exchange. Bronchi are larger in diameter than bronchioles.
