block9_26.jpg - Fig 12. Lung (NO-6-b)A typical bronchiole is shown here. Blood vessels (BV) are adjacent to the bronchiole. The main features of the bronchiolar wall evident in the figure are bundles of smooth muscle (M) and the lining epithelium. The connective tissue is minimal and, at this low magnification, not conspicuous. Nevertheless, the connective tissue is present and separates the muscle into bundles. The connective tissue contains collagenous fibers (CF). Glands are not present in the wall of the bronchiole. Surrounding the bronchiole, are the air spaces or alveoli (A) of the lung.
