Changes in elastic fibres in the small airways and alveoli in COPD alveoli The terminal bronchioles then subdivide into respiratory bronchioles which subdivide into alveolar ducts Numerous alveoli and alveolar sacs alveoli By mapping alveolar development at cellular resolution at a specific position in the branch lineage, we find that alveoli form surprisingly

alveoli The bronchi branch into smaller and smaller passageways until they terminate in tiny air sacs called alveoli The cartilage and mucous membrane of the

alveoli Each person has hundreds of millions of alveoli in their lungs This network of alveoli, bronchioles, and bronchi is known as the bronchial tree The lungs Summary Alveoli are microscopic, balloon-like structures in the lungs that play an essential role in the respiratory system Over time, the
