Left pulmonary artery

Looks like

One of the two large branches of the pulmonary trunk, entering each lung at its root beside the main bronchus.

What it does

Carries oxygen-poor blood from the right heart into one lung.

Keeping it well

A large clot here can cause collapse; long-standing lung disease raises its pressure and strains the right heart.
