Cartilage in the respiratory system, specifically in the trachea (windpipe), plays a crucial role in preventing its collapse, particularly during expiration.
The Role of Cartilage in the Trachea
The primary function of cartilage in the lungs' airway system is to maintain structural integrity. This is especially evident in the trachea.
- Structural Support: Hyaline cartilage rings provide support to the trachea.
- Preventing Collapse: According to the provided reference, the hyaline cartilage layer is both sturdy and flexible, and it "prevents the collapse of the trachea during expiration." This ensures that the airway remains open, allowing for proper airflow in and out of the lungs.
Cartilage and Breathing
Without cartilage, the trachea would be prone to collapsing due to pressure changes during breathing, potentially obstructing airflow. The cartilage rings keep the trachea open, allowing for efficient respiration.
