There is some form of segmental symmetry between the right and left lungs, even though the left lung is smaller and only contains two lobes. In general, each lung has 10 segments: the upper lobes contain 3 segments, the middle lobe / lingula 2 and the lower lobes 5.

The right lung has 2 fissures: the oblique and horizontal fissures. The right lung contains 3 lobes and 10 bronchopulmonary segments: right upper lobe. apical segment. posterior segment. anterior segment. right middle lobe. lateral segment. medial segment.
The left upper lobe lies in the upper aspect of the left hemithorax and contains four bronchopulmonary segments: apicoposterior segment; anterior segment; superior lingular segment; inferior lingular segment; Like all the pulmonary lobes, it is lined by visceral pleura which reflects at the pulmonary hilum where it is continuous with the ...

The lingula is a combined term for the two lingular bronchopulmonary segments of the left upper lobe: superior lingular segment; inferior lingular segment; The two lingular segments are the most anterior of the segments in the left upper lobe lying below the apicoposterior and anterior segments and above the oblique fissure. Radiographic features
The left lung contains two lobes and eight bronchopulmonary segments: left upper lobe. apicoposterior segment. anterior segment. superior lingular segment. inferior lingular segment. left lower lobe. superior segment. anteromedial segment.
In most individuals, the right lung is composed of three lobes subdivided into 10 segments and the left is composed of two lobes and eight segments. They are surrounded by the pleura which separates them from the chest wall. See main article: bronchopulmonary segmental anatomy. The lobes of the lungs are also incompletely separated by fissures.
