Answer:

Less air sacs or surface area = less gas exchage = less oxygen makes it to the blood

Explanation:

Merging lowers the available surface area in lung for gas exchange, thus you cannot exchage the oxygen from your lung into the blood. Even though when you breathe in you take in all the oxygen you possibly can, it does not matter cuz it won't be making it to your blood as efficiently.
