Does the trachea pass through the hilum?

Structures that form the root of the lung enter and exit at the hilum, and allow the root to be connected to the heart and to the trachea. Functionally, this means that the hilum aids the lung roots by anchoring the lungs to the heart, trachea, and surrounding structures.

What structures are in the hilum?

Hilum anatomy and function

• bronchi.
• pulmonary veins.
• pulmonary arteries.
• phrenic nerves.
• lymphatic vessels.
• nodes.
• bronchial arteries.

What direction does the phrenic nerve pass to the hilum of the lung?

The right and left phrenic nerves have a different course in the thorax but as a general rule they descend as lateral as possible whilst keeping in contact with the mediastinal pleura. Both travel anterior to the hilum/bronchus on their respective side.

What structures enter and exit the hilum?

The hilus is the point of entry and exit of the renal arteries and veins, lymphatic vessels, nerves, and the enlarged upper extension of the ureters.

What are the 3 main structures that penetrate the hilum?

Structures entering the hilum include the bronchus, the pulmonary artery, the pulmonary veins, the bronchial arteries and veins, the pulmonary nerve plexuses, and lymphatic vessels.

Which vessel passes directly behind the right hilum?

Both left and right hilum contain a pulmonary artery, pulmonary veins (superior and inferior), and bronchial arteries. Also, in the left hilum, there is one bronchus, the principal bronchus, and in the right hilum, there are two bronchi, the eparterial and hyparterial bronchi.
