Hilum is the region which is located in the central or the medial part of lungs.

The three ‘tubes/structures’ entering and exiting the hilum of the lung are:

Bronchus
Arteries (Bronchial artery and pulmonary arter)
Veins (Bronchial vein and pulmonary vein)

Tubes is afferent to the lungs:

Bronchus: Is the air passage which conducts the air in (afferent) and out (efferent) of the lungs through hilum.
Blood vessel which is afferent to lungs is bronchial artery (supplies oxygenated blood to bronchi and connective tissues of lungs).
Blood vessel which is afferent to lungs is pulmonary artery (brings deoxygenated blood to the lungs from the heart) and enters lungs through hilum.

Tubes are efferent to the lungs:

Bronchus: Is the air passage which conducts the air in (afferent) and out (efferent) of the lungs through hilum.
Blood vessel which is efferent to lungs is bronchial vein (drains deoxygenated blood from bronchi and connective tissues of lungs).
Blood vessel which is efferent to lungs is pulmonary vein (which takes oxygenated blood from the lungs to the heart) and leaves lungs through hilum.
