C, Collapsed bronchiolar epithelial lined alveoli (Lambertosis) can look concerning, but the relationship to the bronchiole confirms a benign metaplastic proliferation (hematoxylin-eosin, original magnifications X10 [A], X2 [B], and X20 [C]).
Measurements in that study were made from a respiratory bronchiole to the edge of the acinus.
Among the cases, abnormal terminal bronchioles and pulmonary vessels showing features of peribronchiolitis and perivasculitis appeared as thickening in the wall of terminal bronchiole and in the wall of pulmonary vessels due to lymphocytic infiltration (Figure-4).
A positive result by light microscopy was granular to diffuse red staining on the apical surface of epithelial cells in trachea, bronchi, and bronchioles and on alveolar cells.
Bronchiole smooth muscle is innervated by both sympathetic (beta-2 adrenergic) and parasympathetic (cholinergic) autonomic nerves, which exert opposite effects on the airways.

Nature, for example, moves oxygen from the atmosphere to mammalian bloodstreams through countless tiny tubes in the lungs called bronchiole, Drost said.
The terminal respiratory unit of the lung from the respiratory bronchiole to the alveolus is called the acinus.
In the study, researchers combined four types of human cells to replicate three-dimensional tissues from the wall of the bronchiole, found deep inside the lung.
He said that asthma attacks occur when the bronchi and bronchiole become inflamed, reducing the space through which air can travel through the lungs and this causes the asthmatic to work harder to move air in and out of the lungs.
After the terminal bronchiole, the following seven generations of dichotomous divisions are called respiratory bronchioles and serve the gas-exchanging parenchyma consisting of budding alveoli.
