Food and liquid both go down the esophagus to the stomach, while air goes down the windpipe or bronchial tubes to the lungs. Both the esophagus and windpipe are connected. Occasionally, a small amount of food or liquid may start to go down the windpipe. Typical involuntary responses would include gagging, coughing, and choking. Difficulty in coughing up the food or liquid may cause a person to panic, while food lodged in the bronchial valve may quickly cause unconsciousness caused by the person being unable to cough out blockage, leading to a lack of of oxygen to the brain.
What They Do. The two openings of the airway (the nasal cavity and the mouth) meet at the pharynx (pronounced: FAR-inks), or throat, at the back of the nose and mouth. The pharynx is part of the digestive system as well as the respiratory system because it carries both food and air. At the bottom of the pharynx, the pathway for both food and air divides in two. One passageway is for food (the esophagus, pronounced: ih-SAH-fuh-gus, which leads to the stomach) and the other for air.
