Root of the lung

Found on the superior mediastinal surface of each lung is its root, by which the lung is connected to the heart and the trachea.

The root is formed by the bronchus, the pulmonary artery, the pulmonary veins, the bronchial arteries and veins, the pulmonary plexuses of nerves, lymphatic vessels, bronchial lymph glands, and areolar tissue, all of which are enclosed by a reflection of the pleura.
