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 trachea is shaped like a pipe. When a person breathes in, the trachea filters the air down into the bronchi, two air tubes that then carry air directly to the lungs. The main organs of the respiratory system are the lungs. They take oxygen into the body and breathe out carbon dioxide. Oxygen is retrieved from the lungs by red blood cells that then carry the oxygen throughout the body to the cells that need it.
