Introduction
Introduction
The trachea consists of:
- Respiratory epithelium (Stratified columnar with cilia creating brush border)
- Lamina Propria with elastic fibers, blood vessels and lymph nodules
- Submucosa with seromucous tracheal glands
- Perichondrium layer
- Hyoid cartilage layer - Covered with adventitia layer
The trachea, or windpipe, is a 9-15 cm long fibrocartilaginous tube of the lower respiratory tract. It forms the trunk of the tracheobronchial tree, or pulmonary conducting zone. The trachea extends between the larynx and thorax, consisting of two parts; cervical and thoracic. It ends at the level of the sternal angle (T5) where it divides into two main bronchi, one for each lung.
