Question
I'm not sure how to answer one of my homework questions.
Is one function of the alveoli to filter out dirt and pollen before it reaches the lung and why or why not. I don't think it is because the alveoli are used to oxgenate the blood, correct. I don't think they filter out dirt or pollen, do they?
