Answer:
lobules, which have alveoli, where oxygen is transferred to the blood
Explanation:
The lungs are separated into lobules by fissures. Each lobule is comprised of tiny air sacs called the "alveoli." The alveoli is responsible for the exchange of oxygen as it receives the oxygen inhaled into the lungs going to the blood.
The right lung consists of the Right Upper Lobe, Right Middle Lobe and Right Lower Lobe. The left lung consists of the Left Upper Lobe and Left Lower Lobe. There are only two lobes in the left lung because it is smaller when compared to the right lung.
