This includes the pulmonary arteries and veins, the primary bronchi and bronchial arteries, and the pulmonary nerve plexuses and lymphatics. The hilum is the place on the lung where these structures enter and leave the lung.

It is the point at which various structures enter and exit the lung. The hilum is surrounded by pleura, which extends inferiorly and forms a pulmonary ligament.
What lobe is the hilum in?

From anterior to posterior, the renal vein exits, the renal artery enters, and the renal pelvis exits the kidney.
