उत्तर
The upper ends of both the oesophagus and the trachea open in the throat next to each other; there is a flap that covers the trachea. When the food is swallowed, the trachea remains closed. But if we eat in a hurry, the food enters the trachea. This causes choking. But due to coordination of the brain, we immediately start coughing, and the food particles are expelled out of the trachea.
