Pulmonary arteries and veins
Bronchial arteries
The left bronchial arteries (superior & inferior) usually arise directly from the thoracic aorta.
The single right bronchial artery usually arises from one of the following:
1) the thoracic aorta at a common trunk with the right 3rd posterior intercostal artery
2) the superior bronchial artery on the left side
3) any number of the right intercostal arteries mostly the third right posterior.
Bronchial veins
