1. Overview
Tổng quan về đường thở
Normally, the lower airway (under the epiglottis) is covered and protected by the epiglottis. When drinking water and swallowing food, the food and drink will go into the esophagus and then into the stomach; without being able to enter the airways. Coughing is a natural response of the body, usually coughing continuously until the foreign body is cleared from the airway.
