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.
The body takes in air rich in oxygen through the nose and mouth. It then travels down through the air tubes (the pharynx and larynx), through the trachea, the bronchial tubes, and into the alveolar spaces. The alveolar spaces are millions of tiny air sacs that have a very thin wall. The alveolar capillary rests immediately on the other side of the alveolar wall.
