Pores of Kohn
|
openings between alveoli, they allow macrophages to pass, purpose is controversial - may be for collateral ventilation or for macrophage migration from one alveolus to an adjacent one

Type III |
Alveolar Macrophage
(has phagocytic abilities, last line of defense, they engulf things such as dust) |
|
|
What monitors your ventilation and tells your brain whether you are breathing too much or too little? (helps regulate CO2)
|
