bronchial vein
The bronchial veins are small vessels that return blood from the larger bronchi and structures at the roots of the lungs. The right side drains into the azygos vein, while the left side drains into the left superior intercostal vein or the accessory hemiazygos vein. The bronchial veins are counterparts to the bronchial arteries. The veins, however, do not return all of the blood supplied by the arteries; much of the blood that is carried in the bronchial arteries is returned to the heart via the pulmonary veins.

Questions
Where is the bronchial vein?
It sits within the cardiovascular system. Only the system is known. The position shown carries almost no spatial information.
What does the bronchial vein connect to?
A kind of: vein.
Is the bronchial vein the same in other species?
Leumas holds the same relationship vocabulary for every species it carries, so where another dataset records this structure you can put the two side by side on /compare.
