Final answer:
The left lung is divided into two lobes, namely the superior lobe and the inferior lobe, to accommodate the heart.
Step-by-step explanation:
The left lung is divided into two lobes: the superior and inferior lobes. These lobes are separated from each other by fissures. The right lung, which is larger, consists of three lobes: the superior, middle, and inferior lobes. The left lung's smaller size allows room for the heart, which is located just left of the center of the chest. Additionally, within each lobe, there are bronchopulmonary segments, which receive air and blood flow from their own tertiary bronchus and artery, respectively.
