Question

how are the lungs designed in human beings to maximise the area for exchange of gases?​

Answer 1

Explanation:

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.

Answer 2

Lungs contain millions of alveoli which provide a surface for the exchange of gases. An extensive network of blood vessels is present in the wall of the alveoli. By lifting our ribs and flatten the diaphragm, the chest cavity becomes spacious. Air is sucked into the lungs and alveoli.
