The alveoli are lined with thin simple squamous epithelium that allows air entering the alveoli to exchange its gases with the blood passing through the capillaries. The one advantage of breathing through the mouth is that its shorter distance and larger diameter allows more air to quickly enter the body.

The epiglottis is also attached to the hyoid bone by the hyoepiglottic ligament which extends from the anterosuperior surface of the epiglottis to the body of the hyoid bone. At the same time, the larynx is pulled superiorly and the cartilaginous epiglottis, its most superior structure, folds inferiorly, covering the glottis (the opening to the larynx); this process effectively blocks access to the trachea and bronchi.
