Bronchial Cartilage: Keeping Airways Open

The bronchi—the airways branching from the trachea into the lungs—are reinforced by C-shaped rings of hyaline cartilage. These incomplete rings are arranged in a spiral pattern, providing:

• Structural support to prevent collapse during exhalation and coughing.
• Patency maintenance ensuring uninterrupted airflow.
• Flexibility at the posterior membranous wall, allowing esophageal expansion during swallowing.

This cartilaginous scaffolding is essential for efficient ventilation and protects the airway from dynamic compression.
