Question

ordering question
click and drag on elements in order
list the correct order for air flow, with the more proximal airway at the top of the list and the most distal airway at the bottom.
instructions
segmental bronchus
t erminal bronchiole
respiratory bronchiole
main bronchus
lobar bronchus
intralobular bronchiole

Explanation:

Airflow in the respiratory system follows a hierarchical structure. The main bronchus is the first major branch from the trachea (most proximal among the given options). It then divides into lobar bronchi (one for each lobe of the lung). The lobar bronchi further divide into segmental bronchi (supplying bronchopulmonary segments). After the segmental bronchi, the airways become smaller - first the terminal bronchioles (non - respiratory, part of the conducting zone), then the respiratory bronchioles (start of the respiratory zone as they have alveoli), and finally the intralobular bronchioles (which are more distal and related to the lobular structure in terms of air distribution to alveoli).

Answer:

1. main bronchus
2. lobar bronchus
3. segmental bronchus
4. terminal bronchiole
5. respiratory bronchiole
6. intralobular bronchiole
