Question

how are lungs designed to maximize the exchange of gases​

Answer 1

Answer:

Lungs play a major role in the respiratory system. In humans, a pair of lungs aredesigned in such a way that they are lined by a thin membrane, the smaller tubes called bronchioles a balloon-like structure called alveoli and network of blood capillaries increase the surface area for exchange of gases.

Alveoli 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.
