Question

How are o2 and co2 transport in human beings how are lungs desingned to maximise the area for exchange gases?

Answer 1

In the lungs the bronchioles terminate in balloon like structure called alveoli.the alveoli contains network of blood cappilaries that increase the surfacearea for exchange of gases.

Answer 2

♤ In the lungs, the air passage that divides into smaller and smaller tubes called bronchi which form bronchioles .

♤ The bronchioles terminate in the balloon like structure called alveoli.

♤ The alveoli present in the lungs provide maximum surface for exchange of gases.

♤ The alveoli have very thin walls and contain an extensive network of blood vessels to facilitate exchange of gases.
