Respiratory Bronchiole
Branching
main bronchi -> lobar bronchi -> segmental bronchi (supply lung bronchopulmonary segments) -> bronchi -> bronchioles (smaller than 1 mm) -> respiratory bronchioles.
Bronchi
- Trachea branches into 2 main bronchi, with a histological structure similar to that of the trachea.
- branches are accompanied by branches of the pulmonary artery, nerves and lymph vessels
- surrounded by a layer of smooth muscle, which is located between the cartilage and epithelium.
Bronchioles
- transition from bronchi to bronchioles the epithelium changes to a ciliated columnar epithelium.
- Smooth muscle present, glands and cartilage are absent.
Respiratory Bronchioles
- first structures that belong to the respiratory portion of the respiratory system.
- wall out-pouchings form alveoli (site of gas exchange)
- end in alveolar ducts
- alveoli - duct or sac.
