Study Notes
Larynx Function
- Acts as a voice box, facilitating sound production for speech.
- Protects the lower respiratory tract by acting as a passageway for air.
- Plays a role in the cough reflex by expelling foreign particles.
Glottis Protection
- The epiglottis covers the glottis during swallowing to block food from entering the larynx.
Division of Trachea
- The trachea divides into the right and left primary bronchi at the level of the 5th thoracic vertebra.
Pharynx Connection
- The oropharynx serves as the common passageway for both food and air, connecting to the pharynx.
Tracheobronchial Support
- Cartilage rings provide structural support to the trachea and bronchi, ensuring they remain open during airflow.
