Solution
Answer:
The lungs of human beings are designed in such a way that it maximizes the exchange of gases.
The human lungs contain millions of alveoli (air sacs).
The presence of millions of alveoli in the lungs provides a large surface area for the exchange of gases. And this availability of a large surface area maximizes the exchange of gases.
