Throat

ThroatThe throat is a multi-purpose pipe that descends from the back of the nose and mouth in the trochee (windpipe) and esophagus (gullet). When you breathe, air passes through the throat and into the trachea on the way to the lungs. When you swallow, chewed food, lubricated with saliva, slides down the throat into the esophagus on its way to the stomach. When you speak, you use the larynx that is located in the throat, at the top of the trachea. From the air, which passes over the vocal cords (tighter tissue covers the larynx), the vocal cords vibrate, creating sounds that the mouth and oral cavity formed in the speech.

Like other parts of the respiratory tract, the throat is also mainly exposed to the risk of infection which often spreads to the upper and lower airways. However, this is not always the disease itself; sore throat sometimes warns about the infectious or inflammatory disease, e.g. acute bronchitis, in another part of the respiratory system.
