CAIE IGCSE Biology EXTENDED 11.1.7 Function of cartilage in the trachea
Practise linking cartilage in the trachea to airway support, airflow and the prevention of collapse during ventilation.
How this is tested
- state that cartilage in the trachea keeps the airway open and prevents collapse
- link C-shaped cartilage rings with support while allowing air to move through the trachea
