Kierra Smith · Answer 1

First, in the lungs are150 a million alveoli (very large surface area) which mean more oxygen is taken in.

Second, of all, the alveoli are covered in capillaries, meaning that gas exchanges happen extraordinarily fast - with each breath.

Luz · Answer 2

First of all, humans have their two lungs to breathe, which are covered in over 150 million alveoli, meaning a very, very large surface area, which means more oxygen is taken in.

Second of all, the alveoli are covered in capillaries, meaning that gas exchanges happen extraordinarily fast - with each breath.

So, yes, they add up to create a large surface area and are covered in capillaries.
