Which pipe does food go down when choking?

When choking, food typically obstructs the trachea, which is the airway pipe that leads to the lungs. The esophagus, on the other hand, is the pipe that carries food to the stomach. If someone is choking, they cannot breathe properly because the trachea is blocked, while food may not have yet entered the esophagus if the choking is immediate. Immediate action is needed to clear the obstruction and restore airflow.
