Answer 2

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 .
