Upper aerodigestive tract means mouth, pharynx and larynx. Air and aliments go through them until trachea then lungs and oesophagus then stomach.

The mouth communicates with the pharynx, where the air and aliments arrive. The air goes then in the larynx, which is continued by the trachea. The aliments go in the hypopharynx, which is continued by the oesophagus.

The larynx contains the vocal cords whose vibration creates the voice. Between the vocal cords there is the epiglottis, which, during the deglutition, will prevent the aliments from going into the larynx and send them into the oesophagus.
