In the root of the right lung, identify:

In the right lung, the right superior secondary bronchus occupies a more superior position than the pulmonary artery, and, therefore, is known as the eparterial bronchus.

In addition to these large structures, attempt to identify the bronchial arteries, which supply oxygenated blood to the tissues of the lungs. These arteries are found on the posterior surface of the primary and secondary bronchi.

Below the root of the lung, identify the pulmonary ligament. It is a reflection of the pleura.
