The structure located between the nasopharynx and the larynx in the respiratory passage is the glottis. It is a part of the larynx and is responsible for regulating the flow of air into and out of the trachea. During swallowing, the flap-like structure called the epiglottis covers the glottis to prevent food particles from entering the respiratory passage. The alveoli, atria, and bronchi are parts of the lungs and bronchial tree, respectively, and are not located in the respiratory passage between the nasopharynx and the larynx.
