Whatever it is, spores or something in the air agitates air/bronchiole passages, and coughing can be excruciating.
Whatever is in the medication, it feels like it subdues the swollen bronchiole passages and breathing is like a breath of fresh air without the constriction.
Albuterol Inhalation Aerosol is a prescription bronchiole throat-spray (in the US) and has always worked for me.
What ever it was, spores in the air or whatever, I tried a bronchiole inhaler and it instantly gave relief and put the coughs to rest.
At the end of each bronchiole are tiny sacs called alveoli, each one of them lined with a thin layer of fluid that keeps each alveolus open.
Specifically the H5N1 (SAa2,3Gal) receptors were found â€œon non-ciliated cuboidal cells at the junction between the respiratory bronchiole and alveolusâ€ and on â€œa substantial number of cells lining the alveolar wall. â€ (This describes the substance of the lung tissue involved in gaseous exchange.)
From there the bronchi divides into multiple smaller bronchiole, none of which contain cartilage or mucus glands in their walls.
Each bronchiole divides into two or more respiratory bronchioles, with scattered alveoli, and each of these again divides into several alveolar ducts, with a greater number of alveoli connected with them.
Each bronchiole ends in grapelike clusters of tiny air sacs called alveoli.
