The genesis of the pulmonary tree and its branches--the mainstem, lobar, segmental and bronchiolar airways--are defined by periods of lung development.
The major pathophysiologic changes in emphysema include chronic infection, excess mucous and inflammatory edema, entrapment of air in the alveoli and bronchiolar obstruction increasing airway resistance.
In the lungs, reduced chloride secretion reduces the salt and water content of bronchiolar mucus and periciliary liquid.
Peripheral increase in vascular resistance can be caused by underlying lung consolidation, atelectasis, or peripheral bronchiolar obstruction.
Organizing pneumonia is diagnosed by its histopathologic pattern of fibroblastic plugs within alveolar ducts and inflammatory changes in the surrounding alveoli with varied bronchiolar involvement.
We move silently and cleanly about our towns or countryside at almost no risk to anyone else, and (this puts us even more on the side of the angels) we leave the air cleaner than we find it, thanks to the trapping of airborne particulate debris by the mucous sheet covering our bronchial and bronchiolar epithelium.
The imidazolines have a lesser myocardial and bronchiolar effect, whereas the amines produce more rapid tachyphylaxis and are less toxic to the nasal cilia.
