Question

How alvoli are designed to maximize the exchange of gases 0 bio?

Answer 1

well alveoli are sac like structure made up of single layer of epithelium tissue filled with alveolar fluid/matrix allowing alveoli to exchange gases while inhaling
since the alveoli is made of single cell layer diffusion of gases form them is possible

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 .
