Embedded in the connective tissue of the hilus (root) of the lungs are all the structures that enter or leave the lungs. This slide has a section of the pulmonary artery, a hilar lymph node, and a part of the primary bronchus. The large pulmonary veins are not present.

Look for bronchioles and respiratory bronchioles and their accompanying arteries. Branches of pulmonary arteries are atypical in that elastic lamellae are continued into even the smallest branches where only two or three layers are present.
