Answer:
The alveoli provide a surface where the exchange of gases can take place. ... The walls of the alveoli are supplied with an extensive network of blood vessels. So lungs maximise the area for gaseous exchange through the presence of large number of alveoli which are richly supplied with blood.

Within the lungs , the air passage
divides into smaller and smaller tubes
called bronchi which in turn form
bronchioles . The bronchioles terminate
in balloon-like structures called alveoli .
The alveoli present in the lungs provide
maximum surface for exchange of gases .
The alveoli have vary thin walls and
contain an extensive network of blood
vessels to facilitate exchange of gases .
