Detailed explanation-1: -Since the heart tilts to the left, the left lung is smaller than the right and has an indentation called the cardiac impression to accommodate the heart. This indentation shapes the inferior and anterior parts of the superior lobe into a thin tongue-like process called the lingual.
Detailed explanation-2: -The left lung is smaller because of the space taken up by the heart (see diaphragm for an image of this). Each lung is separated into lobes branching off the main bronchus; the right lung has three lobes, while the left has only two lobes.
Detailed explanation-3: -The right lung has three lobes and is slightly larger than the left lung, which has two lobes. The lungs are separated by the mediastinum. This area contains the heart, trachea, esophagus, and many lymph nodes.
