They open up to make the lumen larger.
•Beta-agonists for asthma -Dilate bronchioles but speed up the heart because both ß1 and ß2 receptors are stimulated -Specific ß2 -agonists just dilate the bronchioles •Salbutamol (Ventolin) is a specific agonist of the ß2 receptor and provides tremendous relief for asthma sufferers.
The Bronchioles connect the brochi and the alveoli
The drops the ophthalmologist put in my eyes made my pupils dilate.
The walls of the bronchioles are made up of smooth muscle, connective tissue, and epithelial cells.
Acetylcholine causes bronchoconstriction by binding to muscarinic receptors on smooth muscle in the bronchioles, leading to narrowing of the airways. This can result in difficulty breathing and decreased airflow to the lungs.
You are activating the sympathetic nervous system, "fight or flight" mode. Eyes dilate, your heart rate increases, gastrointestinal system slows, bronchioles dilate, etc.
Bronchioles don't have cartilage because they need to be able to constrict and dilate

Your irises may dilate.
The smooth muscle in the walls of the bronchioles is very sensitive to the concentration of carbon dioxide. A rising level of CO2 causes the bronchioles to dilate. This lowers the resistance in the airways and thus increases the flow of air in and out.
No, dilation of the trachea and bronchioles is typically caused by the sympathetic nervous system, which leads to relaxation of smooth muscles in the airways. Parasympathetic activity usually causes constriction of the airways.
light.. or if someones intrerested in you then that happens as an unconcious effect
Nebuliser helps in administration of any type of drug(bronchodilator) till the level of bronchioles. as it creates a mist of a drug instilled by breaking drug particles ,s o that they reach till the bronchioles. so as to dilate the bronchi, with its warm effect also helps in loosening secrections. especially, in cases of COPD, ASTHMA,etc....
The three types of bronchioles are terminal bronchioles, respiratory bronchioles, and conducting bronchioles. Terminal bronchioles are the smallest airways in the respiratory system that lead to the respiratory bronchioles where gas exchange occurs. Conducting bronchioles are larger airways that branch off the main bronchi and help to conduct air to the smaller bronchioles.
There are the bronchi and bronchioles
description of the bronchioles
Pupils "constrict" when light enters, and "dilate "when the lighting dims
