In addition, there was muscular hyperplasia in smooth muscle layers of some vessels and bronchioles
. Due to intense exudate accumulation, congestive atelectasis with different intensities, enlargement of some alveoli in emphysematous fashion and even destruction of morphological structure due to rupture of alveolar walls were observed (Figure 3B-3D).
3RESTRICTED AIR WHEN the bronchioles
become inflamed as a result of the RSV, they restrict the amount of air that can enter the lungs, making it more difficult for children to breathe.
The infection causes the bronchioles
to become inflamed (swollen) and increases the production of mucus.
Les petites bronches (bronchioles
) et les alveoles des poumons se deforment et perdent leur elasticite, puis lesalveoles pulmonaires, qui permettent les echanges gazeux lors de la respiration, sont detruites, c'est ce que l'on designe sous le nom d'emphyseme.
From the VAC, bronchioles
were selected that fulfilled the following characteristics: i) bronchioles
perpendicular to the cut, ii) closed with the presence of smooth muscle.
are found in the respiratory system where air is fed to the alveoli (air sacs) and ultimately the blood stream.
(24) "Bronchiolitis" is often reported in subacute HP, but what that really means is that the chronic inflammatory infiltrate is present in the wall of the bronchioles
as well as in the alveolar interstitium (and rarely present only in the bronchiolar walls and not in the interstitium).
There were bronchioles
entrapped within and at the periphery of the tumor (Figures 4(e) and 4(f)).
In one study that analyzed and compared the high-resolution CT (HRCT) and histopathologic findings of amyloidosis in Sjogren syndrome, the cysts appeared to be located in the distal bronchioles
that were narrowed by amyloid deposition .
He said that asthma attacks occur when the bronchi and bronchioles
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.
In evaluating bronchial deposition, the appropriate particle size varies markedly depending on which of the 1st to 16th branches of the airway (including bronchioles
) are targeted for the treatment.
A bronchodilator is a substance that dilates the bronchi and bronchioles
, decreasing resistance in the respiratory airway and increasing airflow to the lungs.
