What is parenchymal opacities of the lung?
Parenchymal opacification on thin-section CT scans is a nonspecific finding in diseases that affect the air spaces, interstitium, or both but usually indicates potentially treatable or reversible disease.
What does parenchymal abnormality mean?
Parenchymal abnormalities of vascular origin are associated with increased or decreased vessel diameter, vascular compression, or intraluminal filling defect.
What does lung parenchyma mean?
The lung parenchyma is that portion of the lungs involved in gas exchange. The most prominent structure in this region is the alveolus (Figure 1). Each alveolus in the lung parenchyma opens directly into an alveolar duct or occasionally, in a limited number of species, into a respiratory bronchiole.

How many bronchi does the lingular bronchus have?
Two of the tertiary bronchi, the superior lingular bronchus and the inferior lingular bronchus, carry air to the lingula. Upon reaching the lingula, each tertiary bronchus further divides into many bronchioles to deliver air to all of the tissues of the lung.
