Cough

   A rapid expulsion of air from the lungs typically in order to clear the lung airways of fluids, mucus, or material.

RELATED TERMS
--------------------------------------

Lungs
The main respiratory organs in the chest where blood is oxygenated.

Mucus
A substance secreted by various tissues in the body (the mucous membranes) made up of water, mucin (a glycoprotein), salts, and some cells. In the lungs, mucus serves to lubricate the insides of the airways and to trap inhaled foreign particles so that they can be coughed out. In asthma, however, an excess of mucus is produced and can actually block airways. Mucus also tends to be thicker and more viscous in asthmatics.
