What it is
Arises from the right main bronchus only 1–2 cm below the carina, above the pulmonary artery (hence "eparterial"), and splits into apical, posterior and anterior segmental bronchi.
Function
Secondary (lobar) bronchus: conducts air to one lobe of the lung.
Size
About 1–1.5 cm long, 8–10 mm wide.
Clinical note
Lobar bronchi are the level at which the lung is removed in a lobectomy; their walls contain irregular cartilage plates instead of rings.
