Left anterior bronchopulmonary segment
Segmentum anterius pulmonis sinistri (S III) · Levý přední bronchopulmonální segment
Respiratory system
Looks like
A wedge of the upper lobe at the front, with its own airway, artery and drainage — like a slice of cake with the tip at the lung root.
What it does
Takes part in breathing: air and blood meet here to swap oxygen for carbon dioxide.
Keeping it well
Being self-contained, it can be removed alone for small tumours. A cough lasting over three weeks or blood in phlegm needs a doctor.
