There are two bronchopulmonary segments of the lingula: Superior and inferior.

Each of the tertiary bronchi serves a specific bronchopulmonary segment.

This property allows a bronchopulmonary segment to be surgically removed without affecting other segments.

A bronchopulmonary segment is a division of a lung separated from the rest of the lung by a connective tissue septum.

Pulmonary hypoplasia is incomplete development of the lungs, resulting in an abnormally low number or size of bronchopulmonary segments or alveoli.

The lobar bronchi divide into tertiary bronchi, also known as segmentalinic bronchi, each of which supplies a bronchopulmonary segment.

Thus, each bronchopulmonary segment is supplied by a segmental bronchus, and two arteries, a pulmonary artery and a bronchial artery which run together through the center of the segment.

Delineation of the bronchopulmonary segments was made by Dr. John Franklin Huber, Dr. Chevalier Jackson and Dr. Charles M. Norris at Temple University Hospital.

This means that each bronchopulmonary segment is a discrete anatomical and functional unit, and this separation means that a bronchopulmonary segment can be surgically removed without affecting the function of the other segments.
