| The inhaled dust deposited in the bronchioles and alveoli reacts within the lung tissue to form silicotic nodules. |
| We define primary bronchiolar disorders as those diseases in which an isolated pathologic process is limited to bronchioles anatomically. |
| The BO was manifested as branching tongues of myxoid fibrous tissue in respiratory bronchioles and alveolar ducts. |
| Not to be confused with bronchitis, bronchiolitis is an inflammation of the bronchioles, the smallest branches of the bronchial tree. |
| The respiratory bronchioles, alveolar ducts, and alveoli occupy the space between the core and septal structures. |
| The bronchi and bronchioles did not show epithelial changes, and the pulmonary arteries and arterioles were normal in appearance. |
