| 21. | Later divisions including the respiratory bronchiole, alveolar ducts and alveoli, are specialized for gas exchange.
|
| 22. | These spores are �m, allow them to lodge themselves into the terminal bronchioles of the lung.
|
| 23. | The bronchi continue to divide within the lung, and after multiple divisions, give rise to bronchioles.
|
| 24. | Peribronchitis can make the affected bronchioles more easily visible, as is seen in patients with cystic fibrosis.
|
| 25. | Bitolterol relaxes the smooth muscles present continuously around the bronchi and bronchioles facilitating the flow of air through them.
|
| 26. | Also the distal-proximal bronchiole development is affected, resulting in a reduced quantity of airway exchange sites.
|
| 27. | Dilated and thickened terminal and respiratory bronchioles produce cystic airspaces, giving honeycomb appearance on chest x-ray.
|
| 28. | Because radon particles love to cling to surfaces, the branched network of bronchioles in the lungs offers an ample target.
|
| 29. | These consist of a respiratory bronchiole, which branches into alveolar ducts and alveolar sacs, which in turn divide into alveoli.
|
| 30. | These saccules form at the end of the bronchioles and their appearance marks the point at which limited respiration would be possible.
