Study Notes
Trachea Structure
- The trachea's walls are reinforced with C-shaped cartilage, incomplete rings that provide support and flexibility.
- The C-shaped cartilage prevents the trachea from collapsing, ensuring a patent airway.
- The cartilage's flexibility allows for movement and accommodation of the passage of food through the oesophagus, which lies adjacent to the trachea.
- The Trachealis muscle bridges the gap between the ends of the C-shaped cartilage, further stabilizing the tracheal structure.
