The larynx, often called the voice box, is a crucial part of the human body located in the neck. It plays a key role in producing sound when we speak or sing. The larynx contains vocal cords that vibrate as air passes through them, creating sound waves. It also helps protect the airway during swallowing, preventing food and liquids from entering the lungs. In addition to its role in speech, the larynx is important for breathing. It connects the throat to the trachea, allowing air to flow in and out of the lungs. The larynx also helps regulate airflow, which is essential for activities like singing and playing wind instruments.
