Abstract
Respiratory bronchioles represent a crucial transition point in the respiratory system, linking the conducting and respiratory zones. These small airways, characterized by alveolar outpouchings and a unique epithelial lining, play a vital role in gas exchange and airway regulation. Their structure includes smooth muscle and elastic fibers, which facilitate dynamic changes in airflow. Furthermore, respiratory bronchioles contribute to pulmonary defense through the secretion of surfactant and immune responses. Pathological alterations in these structures are significant in various pulmonary diseases, including chronic obstructive pulmonary disease (COPD), asthma, and bronchiolitis, underscoring their clinical relevance. Understanding the anatomy and function of respiratory bronchioles is essential for diagnosing and managing respiratory conditions effectively. This article reviews the structural and functional aspects of respiratory bronchioles, alongside their implications in respiratory health and disease.
