The respiratory bronchioles
include alveoli periodically along their surface.
Trachea and lung (including bronchus, bronchiole
, and pulmonary alveoli) from 3 animals per species were examined.
ranging from approximately 1 mm down to approximately 0.
Lower bronchi and bronchioles
have no cartilage and may collapse during forced expiration.
The injected stem cells differentiated into new bronchioles
, alveoli and pulmonary vessel cells that not only formed new lung tissue, but also integrated structurally to the existing lung tissue in the mice.
10) Finally, in immunocompromised patients, innumerable Cryptococcus yeasts grow in sheets within alveolar spaces, alveolar septa (interstitium), and alveolar septal capillaries and bronchioles
, with little or no inflammatory reaction.
Adenocarcinoma-the most common type of lung cancer-tends to originate along the outer edges of the lungs in the small bronchi or smaller bronchioles
It's caused by respiratory syncytial virus (RSV) which affects the bronchioles
, the tiny airways deep in the lungs.
Your windpipe is the main trunk; it divides into two branches, the main bronchi, one to each lung, and these continue to branch into smaller air carrying tubes, the bronchi, then the twigs or bronchioles
which carry air to the alveoli, which are the equivalent of the leaves.
The cough is a protective reflex mechanism that removes foreign material and secretions from the bronchi and bronchioles
of the airways (foreign objects, catarrhs of the respiratory system, etc.
These nerves stimulate visceral organs such as the heart muscles and other smooth muscles found in bronchioles
, arteries and veins.
With time, a fibrous and leukocytic infiltration develops around blood vessels, alveolar ducts, and bronchioles
, often obliterating the vessel lumen.
The drug increases heart rate and blood pressure but also dilates the bronchioles
in the lungs, making breathing easier.
The walls of the bronchioles
- the tiny airways in the lungs - swell and produce mucus which leads to the sufferer having difficulty breathing.
For people with asthma, the tendency of their bronchioles
(BRONK-ee-oles), or small airways in the lungs, to overreact and constrict is often present from birth.
