Respiration is the process of taking in oxygen and exchanging it with carbon dioxide. * muscles in the neck, back, and abdomen. Inhalation to exhalation ratio is 10:90: the phonatory system. Consists of the larynx which is a part of the pharynx. *we really care about arytenoids, on each arytenoid there are two strips of epithelial cells, when air is passed over them, they vibrate and create sounds. Two foldings of membrane: they are attached to cartilages (arytenoids) in the larynx. Adduction: (together), the vocal folds are coming together. Abduction: (apart), the vocal folds are coming apart. *they do this very quickly and produce sound. To provide resonating chamber for the air flow. Resonation is the bouncing around of vibrating air in a certain space, makes sound. Our voice sounds the way it does because of the space that our voice has to resonate in. Velopharyngeal port: important for shepherding air between the oral and the nasal cavity.
