Detailed explanation-1: -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-2: -The right and left lung anatomy are similar but asymmetrical. The right lung consists of three lobes: the right upper lobe (RUL), the right middle lobe (RML), and the right lower lobe (RLL). The left lung consists of two lobes: the left upper lobe (LUL) and the left lower lobe (LLL).
Detailed explanation-3: -The height of a normal adult lung is 27 cm at total lung capacity, but in the range of normal breathing it is approximately 24 cm in height. Externally, the lungs are paired structures that, with the mediastinum, fill the thoracic cavity.
