What is the glottis?

The glottis refers to the space between the vocal cords, which are located in the larynx, or voice box. This area plays a crucial role in respiration and phonation (the production of sound). The vocal cords can open and close, allowing for control over airflow during breathing and enabling sound production when they vibrate as air passes through them. Understanding the anatomy of the glottis is fundamental for healthcare professionals, especially in airway management, because any obstruction or dysfunction in this region could impact a patient's ability to speak or breathe properly.

Other options pertain to different anatomical structures but do not accurately define the glottis. The area between the lungs refers generally to the mediastinum, the branching area of the bronchi involves the tracheobronchial tree, and a protective reflex of the airways describes mechanisms like coughing or swallowing, which are not specifically related to the glottis itself.
