Aus Dornheim Anatomy
The wall of the bronchi basically consists of three layers. The tunica mucosa contains the respiratory epithelium (ciliated epithelium/lamina epithelialis). Dirt and mucus are transported through this towards the pharynx. Furthermore, the respiratory air is warmed up through this layer due to the high blood circulation. The tunica mucosa contains elastic fibers that serve to adapt to the variable thoracic volume. Furthermore, this wall layer is involved in immune defense and forms mucus through seromucous glands contained in the lamina propria.
