Final answer:
The glottic opening (Larynx) is responsible for speech production through the vibration of the vocal cords and for protecting the airway during swallowing by using the epiglottis to cover the trachea, helping to prevent choking. The correct option is a) Speech production and airway protection
Step-by-step explanation:
The functions of the glottic opening (Larynx) are speech production and airway protection. The larynx, commonly known as the voice box, houses the vocal cords which vibrate to produce sound when air passes through them. This allows for vocal sounds to be made. Additionally, the larynx plays a crucial role in protecting the respiratory tract during the process of swallowing.
A flap of tissue called the epiglottis closes over the entrance to the larynx, preventing food and liquid from entering the trachea and potentially causing choking. If food or another object does start to enter the larynx, it can trigger a cough reflex, which serves to eject the material and prevent it from moving deeper into the respiratory system. The correct option is a) Speech production and airway protection
