=== Slide 93, Hilus (Root) of the lung, adult male. (H&E) ===

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.
*The large open spaces are alveolar ducts. In a good longitudinal section, pulmonary alveoli making up their wall may be seen.
Slides 106, and 108 are from animals, and slide 33 is from a child. Each slide does not contain all the desired structures but between them, a total picture can be conceived. Slides 110 and 112 are from an adult male. The bronchi are much larger, and are typical for bronchi of those sizes.

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.
=== Slide 110. Segmental bronchus (branch of a lobar bronchus), 62 year-old male (H&E) ===
Study the bronchus as in slide 112. The structure is similar except that the cartilage plates are smaller and farther apart.
