Pulmonary artery

 

The pulmonary artery literally wraps around the upper lobe bronchus. During its course the pulmonary artery provides several branches.

As it passes over the bronchus, it gives off a large branch for the upper division bronchus, and then two or three branches for the lingula.

The veins appear in direct contact with the upper lobe and main stem bronchi.
