Explanation:
Detailed explanation-1: -The left lung consists of two lobes: the left upper lobe (LUL) and the left lower lobe (LLL). The right lobe is divided by an oblique and horizontal fissure, where the horizontal fissure divides the upper and middle lobe, and the oblique fissure divides the middle and lower lobes.
Detailed explanation-2: -The transverse fissure overlies the fourth rib to meet the oblique fissure at the level of the mid axillary line. The presence of the transverse fissure results in three lobes on the right lung while the left lung presents two lobes.
Detailed explanation-3: -The right and left lung anatomy are similar but asymmetrical. The right lung consists of three lobes, and the left lung consists of two lobes.
