Solution
The correct option is D Bronchi
At the same time, carbon dioxide (CO2) is transmitted from the blood capillaries into the alveoli and then expelled through the bronchi and the upper respiratory tract. The inner surface of the lungs where the exchange of gases takes place is very large, due to the structure of the air sacs of the alveoli.So, the correct option is 'Bronchi'.
