Airway in a person with sleep apnea

Airway in a person with sleep apnea
Normally when a person sleeps, the airway remains open, and air can pass from the nose and mouth to the lungs. In a person with sleep apnea, parts of the throat and mouth drop into the airway and block off the flow of air. This can cause loud snoring and interrupt breathing for short periods.
