Question

Place the following structures in order that air passes through to reach the alveoli: alveolar ducts, alveoli, bronchioles, lobar bronchi, main bronchi, respiratory bronchioles, segmental bronchi, smaller bronchi, terminal bronchioles, and trachea.

Answer 1

D. Trachea, bronchi, bronchioles, alveoli

Step-by-step explanation:

During inspiration, incoming air travels through the following structures, in which order?

Bronchioles, bronchi, trachea, alveoli

Alveoli, trachea, bronchioles, bronchi

Bronchi, bronchioles, alveoli, trachea

Trachea, bronchi, bronchioles, alveoli

Answer 2

1. Trachea

2. Main bronchi

3. Lobar bronchi

4. Segmental bronchi

5. Smaller bronchi

6. Bronchioles

7. Respiratory bronchioles

8. Terminal bronchioles

9. Alveolar ducts

10. Alveoli

Step-by-step explanation:

The bronchial tree begins with the trachea and branches into smaller ducts that eventually lead the air to the alveoli, where oxygen performs the gas exchange with carbon dioxide from deoxygenated blood.

The trachea branches into the main bronchi, each one branches into the lobar bronchi (the bronchi that enters into the lungs) in the left lobe we found two lobar bronchi and in the right lobe three lobar bronchi, each lobar bronchi divides further into segmental bronchi, which branches into smaller bronchi, these branch more and more into small conducts named bronchioles until they reach the alveoli (tiny air bags at the end of the terminal bronchioles that are in contact with the capillaries for gas exchange)
