Explanation:
Why are alveoli so small and uncountable in numbers?
To increase the exchange of gases in the lungs, alveoli are uncountable in number. They are too tiny to fit in alveolus numbers and boost gas exchange. The body can absorb much more oxygen than just two enormous ' empty bags ' if our lungs were.
