Final answer:
The right lung has three lobes: superior, middle, and inferior, while the left lung has two lobes: superior and inferior. Each lung is further divided into bronchopulmonary segments, which receive air and blood supply. The lobules of the lungs are separated by connective tissues.
Step-by-step explanation:
The right lung has three lobes: the superior, middle, and inferior lobes. The left lung has two lobes: the superior and inferior lobes. Each lobe of the lung is further divided into smaller divisions called bronchopulmonary segments. These segments receive air from their own tertiary bronchus and are supplied with blood by their own artery.
Additionally, each lobule of the lung receives its own large bronchiole with multiple branches. These lobules are separated from each other by interlobular septa, which are composed of connective tissue.
