Editing Lung (section)

====Segments====
The primary bronchi enter the lungs at the hilum and initially branch into [[Bronchus|secondary bronchi]] also known as lobar bronchi that supply air to each lobe of the lung. The lobar bronchi branch into [[Bronchus|tertiary bronchi]] also known as segmental bronchi and these supply air to the further divisions of the lobes known as [[bronchopulmonary segment]]s. Each bronchopulmonary segment has its own (segmental) bronchus and [[artery|arterial supply]].<ref>{{cite web|last1=Jones|first1=Jeremy|title=Bronchopulmonary segmental anatomy {{!}} Radiology Reference Article {{!}} Radiopaedia.org|url=https://radiopaedia.org/articles/bronchopulmonary-segmental-anatomy-1|website=radiopaedia.org|language=en}}</ref> Segments for the left and right lung are shown in the table.<ref name="pmid1">{{cite journal|last1=Arakawa|first1=H|last2=Niimi|first2=H|last3=Kurihara|first3=Y|last4=Nakajima|first4=Y|last5=Webb|first5=WR|title=Expiratory high-resolution CT: diagnostic value in diffuse lung diseases|journal=American Journal of Roentgenology|date=December 2000|volume=175|issue=6|pages=1537–1543|pmid=11090370|doi=10.2214/ajr.175.6.1751537}}</ref> The segmental anatomy is useful clinically for localising disease processes in the lungs.<ref name="pmid1" /> A segment is a discrete unit that can be surgically removed without seriously affecting surrounding tissue.<ref name="Harper">{{cite book|last1=Tortora |first1=Gerard |title=Principles of anatomy and physiology |date=1987 |publisher=Harper and Row| location=New York |isbn=978-0-06-350729-6 |page=564 |edition=5th}}</ref>
