  2. Airway remodelling - Wikipedia

    en.wikipedia.org/wiki/Airway_remodelling

    Airway remodelling is a multifaceted process involving multiple airway tissues. These include goblet cell hyperplasia, leading to increased mucus production, and airway smooth muscle hypertrophy (or smooth muscle cell hyperplasia), leading to the release of pro-inflammatory and pro-fibrotic messengers contributing to subepithelial fibrosis.

Asthma, bronchiectasis, and chronic obstructive pulmonary disease (COPD) that includes chronic bronchitis, and emphysema, are all obstructive lung diseases characterised by airway obstruction. This limits the amount of air that is ...

  4. Asthma - Wikipedia

    en.wikipedia.org/wiki/Asthma

    Asthma is a common long-term inflammatory disease of the airways of the lungs. [4] Asthma occurs when allergens, pollen, dust, or other particles, are inhaled into the lungs, causing the bronchioles to constrict and produce mucus, which then restricts oxygen flow to the alveoli.

    en.wikipedia.org/wiki/Bronchus

    A bronchus (/ ˈ b r ɒ ŋ k ə s / BRONG-kəs; pl.: bronchi, / ˈ b r ɒ ŋ k aɪ / BRONG-ky) is a passage or airway in the lower respiratory tract that conducts air into the lungs.The first or primary bronchi to branch from the trachea at the carina are the right main bronchus and the left main bronchus.

  6. Bronchial thermoplasty - Wikipedia

    en.wikipedia.org/wiki/Bronchial_Thermoplasty

    Bronchial thermoplasty [1] is a treatment for severe asthma approved by the FDA in 2010 involving the delivery of controlled, therapeutic radiofrequency energy to the airway wall, thus heating the tissue and reducing the amount of smooth muscle present in the airway wall.

    This is also a shorter procedure with a single-shot circumferential approach, eliminating fluoroscopy and ancillary devices, with a universal catheter design suitable for diverse airway anatomies. Asthma and COPD are among the most prevalent chronic diseases globally, affecting over 600 million people.

  8. Bronchiole - Wikipedia

    en.wikipedia.org/wiki/Bronchiole

    The bronchioles (/ ˈ b r ɑː ŋ k i oʊ l s / BRONG-kee-ohls) are the smaller branches of the bronchial airways in the lower respiratory tract.They include the terminal bronchioles, and finally the respiratory bronchioles that mark the start of the respiratory zone delivering air to the gas exchanging units of the alveoli.

  9. Obstructive lung disease - Wikipedia

    en.wikipedia.org/wiki/Obstructive_lung_disease

    Asthma is an obstructive lung disease where the bronchial tubes (airways) are extra sensitive (hyperresponsive).The airways become inflamed and produce excess mucus and the muscles around the airways tighten making the airways narrower.
