Answer 1

because of villi as it increase surface area for absorption... and villi also exchange gases... villi absorb oxygen and release co2.... it is surrounded by alveoli...

thankss... ✌✌

Answer 2

_____________________________

There are millions of alveoli in the lungs.

The presence millions of alveoli in the lungs provides a very large area for the exchange of gases.

And the ability of large surface area maximize the exchange gases.

For example– if all alveoli from the to human lungs are unfolded, they would give an area of about 80 square metres ( which is nearly the size of a Tennis Court ).
