A cough is a sudden, forceful release of air from the lungs. A cough is usually caused by a buildup of phlegm[?] in the trachea. It can also be caused by food going down the trachea instead of the esophagus, although this usually results in choking instead. When someone is coughing a lot, they are usually sick. People can also have a chronic cough, see Chronic cough: causes and cures (http://familydoctor.org/handouts/237.html).
