Use your brain power!
Why do we sometimes choke suddenly while eating?
उत्तर
The upper ends of both the esophagus 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.
