How to use Bronchioles in a sentence
The respiratory bronchioles have single alveoli off their walls.
When these bronchioles are infected, they become inflamed, and breathing may become difficult.
These then branch to give rise to several orders of progressively smaller airways called bronchioles, the smallest of which are called terminal bronchioles.
Researchers chemically modified adrenaline to find molecules that would have the same effect in dilating the bronchioles but without the stimulation of the heart.
These medicines, properly known as bronchodilators, have a relaxing effect on the muscle surrounding the bronchioles.Advertisement
All other particles that are too small to impact will be carried deep into the lungs and reach the terminal bronchioles and alveoli.
These are supplied with air by small bronchioles, which are in turn supplied by bronchi that are fed from the trachea.
Alveoli-The tiny air sacs clustered at the ends of the bronchioles in the lungs in which oxygen-carbon dioxide exchange takes place.
Bronchoscopy-A procedure in which a hollow tube (bronchoscope) is inserted into the airway to allow visual examination of the larynx, trachea, bronchi, and bronchioles.
The bronchioles and bronchi normally produce a thin, clear mucus that traps foreign particles including bacteria and viruses.Advertisement
The bronchioles are small branches off of the more major bronchi or airway tubes that run through the lungs.
Breathing problems occur in RSV infections because the bronchioles swell, making it difficult for air to get in and out of the lungs.
Each bronchus divides into tubes of smaller and smaller diameter, finally ending in the terminal bronchioles.
The alveoli, in which oxygen and carbon dioxide are exchanged, are clustered at the ends of the bronchioles.
Lung stroma, the tissue of the lung, serves a supportive role for the bronchi, bronchioles, and alveoli.Advertisement
Bronchoscope-A lighted instrument that is inserted into the windpipe to view the bronchi and bronchioles, to remove obstructions, or to withdraw specimens for testing.
The changes that take place in the lungs of people with asthma make the airways (the "breathing tubes," or bronchi and the smaller bronchioles) hyper-reactive to many different types of stimuli that do not affect healthy lungs.
The medication is used to treat asthma because it dilates the bronchioles and bronchi.
