Asthma, a disease that affects the
small airways of the lungs, is the most common long - term disease in children, according to area health - care professionals.
They found that infection of the
narrowest airways of the lung by PIV3 alone caused moderate levels of inflammation, but after infection by PIV3 expressing RSV NS2, the epithelial cells lining the narrow airways were shed rapidly into the airway lumen.
To create the effect of tobacco smoke on cells, Vaz, Baylin and their colleagues began their studies with human bronchial cells, which line
the airways of the lungs, and grew them in a laboratory.
Even a light breeze can carry the spores aloft, and when inhaled, they can penetrate deep inside
the airways of the lungs.
This method is carried out under sedation while the patient is still conscious and uses ultrasound to guide a sampling needle down and through
the airways of the lungs.
All the familiar asthma symptoms — coughing, wheezing, shortness of breath, and difficulty breathing — occur because
the airways of the lungs, known as bronchial tubes, become narrowed and inflamed.
Asthma is a long term inflammatory disease that involves
the airways of the lungs.
The airways of the lungs, called bronchial tubes, become inflamed.
One possible explanation is that the allergic inflammation that causes atopic dermatitis may make
the airways of the lungs more prone to inflammation as well.
For example, in humans we know that while actual symptoms of asthma occur in episodes,
the airways of the lung are diseased all the time.
Once asbestos fibers become airborne, they are so small that they can easily lodge deep into the small
airways of the lungs.
These fibers are small enough to work their way into the small
airways of the lungs, where they can't be cleared out by coughing.
Asthma is defined as a disorder that causes
the airways of the lungs to swell and narrow, leading to shortness of breath, wheezing, chest tightness and coughing.
Asthma is usually defined as a disorder that causes
the airways of the lungs to swell and narrow, thus constricting airflow.
