respiratory portion The respiratory portion of the pul- monary system includes the remaining branches of the bronchial tree, alveolar ducts, alveolar sacs, and alveoli.
Alveoli are not only found in the respiratory bronchioles; large numbers of alveoli branch off of the alveolar ducts and alveolar sacs.
Alveolar sacs (clusters of alveoli) and alve- oli branch off of alveolar ducts, which contain smooth muscle cells, elastic fibers, and collagen fibers.
Elastic and reticular fibers are found where the alveoli arise from the respiratory bronchioles, alveolar ducts, or alveolar sacs.
number of alveoli per unit of lung volume; loss of alveo- lar wall tissue; and increased size of the respiratory bron- chioles, alveolar sacs, and alveolar ducts.
