The alvelolus is responsible for the exchange of gas inside different chambers of the lungs and therefore they help a lot in making the ventilation and the exchange of oxygen possible.
It all depends on the surface area of the alveolus, the amount of air to be exchanged and also the diffusion of carbon dioxide from a region of higher concentration to that of lower concentration.
