• Nose --> trachea --> bronchi --> bronchioles --> alveoli

• Nose --> bronchi --> trachea--> alveoli --> bronchioles

• Nose --> bronchi --> alveoli --> bronchioles --> trachea

• Nose --> bronchioles --> bronchi --> alveoli --> trachea

Gas exchange happens between which two structures?

• Capillaries and bronchi

• Capillaries and alveoli

• Capillaries and bronchioles

• Bronchi and alveoli

• Bronchioles & alveoli

Why do alveoli have thin walls?

• So that digestion can function properly.

• So carbon dioxide can be absorbed rapidly into the blood in the lungs.

• So oxygen can be absorbed rapidly into the blood in the lungs.

• So an exchange can take place between the alveoli and bronchi.

• So oxygen can be absorbed rapidly into the blood in the heart.
