Question

The larynx routes air and food into their proper channel and plays an important role in speech production. What is the function of the larynx?

1) To filter air and food particles
2) To produce sound for speech
3) To regulate the flow of air and food
4) To protect the trachea and esophagus

Answer 1

The larynx has multiple functions, including regulating the flow of air and food, producing sound for speech, and protecting the trachea and esophagus.

Step-by-step explanation:

The larynx, also known as the voice box, has several important functions. One of its main functions is to regulate the flow of air and food, ensuring that they are routed into their proper channels. The larynx also plays a crucial role in speech production by containing the vocal cords, which vibrate when air flows over them, producing sound.

Additionally, the larynx helps protect the trachea and esophagus from any aspirated food. When swallowing occurs, the epiglottis, a flap of tissue in the larynx, closes over the larynx's entrance, preventing food from entering and potentially causing choking.
