51.BronchialTree_low.jpg Composite image showing the bronchial tree and corresponding histology of airway segments. • Left diagram: Outlines the branching from trachea to alveoli, labeling trachea, primary, secondary (lobar), and tertiary (segmental) bronchi, bronchioles, terminal bronchioles, respiratory bronchioles, and alveoli. • Right panels: 1. Pseudostratified ciliated columnar epithelium with goblet cells, basal cells, smooth muscle, and hyaline cartilage (bronchus). 2. Simple ciliated columnar epithelium with smooth muscle (bronchiole). 3. Simple cuboidal epithelium with club cells (terminal bronchiole). The image illustrates epithelial transitions and structural changes along the conducting airway.
