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.
Nose or mouth. The nose is the best route for air to get into the lungs, as it is a better filter than the mouth. The nose decreases the amount of irritants that reach the lungs, whilst also heating and adding moisture to the air. Mouth breathing is usually needed when exercising or when more air is needed, because the nose is not the most efficient way of getting large amounts of air into the lungs. Journey down the windpipe. After entering the nose or mouth, air travels down the trachea or windpipe. The trachea is the tube lying closest to the neck. Behind the trachea is the oesophagus or food tube. Air moves down the trachea when we inhale and food moves down the oesophagus when we eat. The path air and food take is controlled by the epiglottis, a gate that prevents food from entering the trachea.
