The organs of speech and their work. The active and passive organs of speech

Organs of speech are: nasal cavity (полость носа), lips, teeth, alveolar ridge, ‘larynx(гортань), palate (soft and hard), uvula(язычок), tongue (tip, blade(передняя часть), front, back), epiglottis(надгортанник), pharynx(глотка), vocal cords, and tra’chea(трахея).
The air stream released by the lungs goes through the windpipe (дыхательное горло) and comes to the larynx, which contains the vocal cords. The vocal cords are two elastic folds (изгибы) which may be kept apart or brought together (сведены вместе). The opening between them is called the glottis (голосовая щель). If the tense(напряженный) vocal cords are brought together, the air stream forcing an opening makes them vibrate and we hear some voice.
