Question

How are lungs designed to maximize the area for exchange of gases

Answer 1

Answer:

In the lungs, the air passage divides into smaller tubes, called bronchi which in turn form bronchioles. ... The presence of alveoli in the lungs provides a very large surface area for the exchange of gases and this availability of large surface area Maximise

There interior of lungs are provided with many ballon like tiny structures called alveoli. These provide a surface where exchange of gases can take place. The walls of alveoli show an extensive network of blood vessels.

There are about 300 million alveoli in each lung. These alveoli maximise the area for exchange of gases.s the exchange of gases

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 .
