Document Summary
Intrapulmonary bronchus: large structure, only a portion of a cross-section (portion of a wall) can be seen in the field of vision of light microscopy. Any time you see this wavy structure with a piece of cartilage you will classify the structure as the pulmonary bronchus. Note: as you move distally (towards the lungs) in the respiratory system, structures get smaller in diameter and also become more branched. Ex: pulmonary bronchus drawing showing: the wavy surface of the pulmonary bronchus (folded mucosa; epithelium and lamina propria) October 19th, 2017: the smooth muscle cells crossing each other. General plan of the regular bronchiole (layers: mucosa, epithelium covering: If you look around, you will see a lot of lung tissue surrounding the bronchiole (is this lung tissue adventitia?) October 19th, 2017: has no hyaline cartilage and has no goblet cells, therefore it must be a bronchiole (can"t be mistaken for a bronchus)
