Detailed explanation-1: -The left lung consists of two lobes: the left upper lobe (LUL) and the left lower lobe (LLL).
Detailed explanation-2: -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.
Detailed explanation-3: -The left lung has only two formal lobes because of the space taken up in the left side of the chest cavity by the heart, though it does have the lingula, which is similar to a lobe.
Detailed explanation-4: -The right lung is larger and weighs more than the left lung. 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.
