Think about a parking lot - it's a flat surface, and you can park about 100 at a time. Now let's say that you take that parking lot, and build up some more levels and make it into a parking garage - you can now fit about 500 cars in there at a time by increasing the parkable surface area by building up the lot.
Your lungs work in a similar fashion. Oxygen can only be absorbed by the surface of the lung - if your lungs were smooth had less surface area, you could absorb less oxygen. By building up these aveoli, the lung's surface is increased and more oxygen can be absorbed without needing your lungs themselves to grow larger.

The lungs have a pseudofractalline shape. The surface is compacted without reducing its area by folding it into large numbers of aveoli.

The larger surface area, The more oxygen your blood can absorb through your lungs

Hi. The process of absorbing O2 and releasing CO2 is not too efficient. The surface area determines how much energy we can produce, more is better.

The greater the surface area, the more gas exchange can occur. That means you can expel more carbon dioxide and more oxygen can bring in.
