If we laugh when are eating, the epiglottis might not close in time. A piece of food, like John's sandwich, can slip down into the trachea. Most of the time it's no big deal. Our body makes us cough and force it back up. But when someone is truly choking it means the food or object is completely blocking the airway and air cannot flow into and out of the lungs. The person cannot cough the object out. They cannot breathe, talk or even make noise. They may grab at their throat or wave their arms. If the trachea remains blocked , their face might turn birght red or even blue.
The body needs oxygen to stay alive. When oxygen cannot reach the lungs and the brain, a person can become unconscious, sustain brain damage and even die within minutes. That is what makes choking such a serious emergency.
