Occasionally, a person may choke when food gets past the epiglottis or sticks to a structure within the pharynx and blocks the airway. The vocal folds contract to catch the blockage before it passes into the trachea. Coughing pushes air out of the lungs to force the blockage out of the airway. Sounds are produced in the larynx by the movement of air through the larynx and by the vocal folds, a pair of movable folds in the mucous membrane.
Air is forced in and out of your lungs by movements of your diaphragm and other breathing muscles. When you breathe in, your breathing muscles contract, pulling your ribs up and out. The space within your chest increases and reduces the air pressure inside your lungs. As a result, air flows into your lungs.our lungs are a pair of large sponge-like organs that almost fill your chest cavity. Your left lung is slightly smaller than your right lung, to make space for your heart. When you breathe in, you suck air in through your nose and mouth and down a tube called the trachea.
