Glottis – The glottis is the then opening to the larynx that subsequently leads to the esophagus. Esophagus – The tube that connects the mouth to the stomach.

Does the glottis lead to the lungs?

The glottis opens directly into a boxlike larynx. This voice box occurs in all amphibians but is anatomically most complex in frogs. The larynx exits into the trachea; the latter bifurcates into the bronchi and then into the lungs.

Where does air go after the glottis?

During inspiration, fresh air enters the respiratory system through the pared external nares (nostrils; shown here) and/or the oral cavity to the pharynx. Air then travels through the glottis into the trachea, through the bronchi and bronchioles to reach the alveoli.
