The glottis is a vital part of the larynx that allows air to pass through and into the trachea. It consists of a narrow opening that opens and closes as we breathe, speak, and swallow. It is responsible for regulating airflow during breathing and is essential for speech production. The glottis is made up of two vocal folds or cords that vibrate as air passes through, producing sound. The size of the glottis opening can also be adjusted for sound variation. Malfunction of the glottis due to disease or injury can lead to respiratory distress or speech problems. Thus, it is important to be mindful of its function and potential problems that could arise.
