Segmental Anatomy Of Lungs
The segmental conception of pulmonary anatomy is not new, but has become increasingly important in recent years. A bronchopulmonary segment is defined as that area of lung supplied by a principal branch of a lobar bronchus. On this basis, each lung is divided into a convenient number of major segments.
there are 2 regions of the left lung in which 2 segments are joined as 1 as they have a common tertiary (segmental) bronchus: left upper lobe apicoposterior segment; left lower lobe anteromedial segment; Right lung. The right lung is subdivided into three lobes with ten segments.
