hilum

Anatomy.—Hilum is a generic term that describes the indentation in the surface of an organ, where vessels and nerves connect with the organ. It is the site on the medial aspect of the lung where the vessels and bronchi enter and leave the lung. Radiographs and CT scans.—A hilum appears as a composite opacity at the root of each lung produced by bronchi, arteries, veins, lymph nodes, nerves, and other tissue. The terms hilum (singular) and hila (plural) are preferred to hilus and hili respectively; the adjectival form is hilar. [Fleishner Society]
