The function of the alveoli is to exchange oxygen in the air for carbon dioxide in the blood.
The correct function of the alveoli is to exchange oxygen in the air for carbon dioxide in the blood. To arrive at this answer, we can eliminate the other options that are incorrect:
- "Carry oxygenated blood away from the heart" is performed by arteries, not alveoli.
- "Hold receptors for the sense of smell" is the function of olfactory cells in the nose, not alveoli.
- "Exchange oxygen in the blood for carbon dioxide in the air" is the opposite of what alveoli actually do.
Therefore, the correct function of alveoli is to exchange oxygen in the air for carbon dioxide in the blood.
