The human left lung, unlike the right, contains no middle lobe. However, the term lingula is used to denote a projection of the upper lobe of the left lung that serves as the homologue. Some sources define the lingula as a distinct lobe.
There are two bronchopulmonary segments of the lingula: Superior and inferior.
It is thought that the lingula of the left lobe is the remnant of the middle lobe of the left lung, which has been lost through evolution, but this cannot be proven.
