Latin	hilum pulmonis
Gray's	subject #240 1095

Above and behind the cardiac impression is a triangular depression named the hilum, where the structures which form the root of the lung enter and leave the viscus. These include the pulmonary artery, superiormost on the left lung, the superior and inferior pulmonary veins, lymphatic vessels and the bronchus, with bronchial vessels surrounding it. The pulmonary ligament droops down from the hilum of the lung and terminates in a free, or falciform, edge.

The area around the hilum is called "perihilar".
