Sneeze:
An Involuntary of air through the mouth and nose. Nerve endings in the nose cause you to sneeze in order to get rid of irritating particles in your nose. Cold air may also induce sneezing. A sneeze may produce an air speed of up to 103 miles per hour and expel up to 100,000 droplets of mucus and microorganisms. For this reason, unless you adequately cover your mouth and nose, your sneeze may be harmful to other people.

Cough:
An abrupt expulsion of air, ridding the Lungs of harmful substances when the lining of the respiratory tract becomes irritated. Coughing may also be a deliberately effort to clear the throat or the bronchi. Like sneezing, coughing can spread germs that cause disease.

Hiccup:
A sudden, Involuntary intake of air caused by a spasmodic contraction of the diaphragm. These abrupt contractions may be caused by irritating of the organs near the diaphragm. The spasm draws air into the Lungs through the larynx. As the air is pulled into the larynx, it strikes the epiglottis, causing the vocal cords to vibrate. This produces the hic sound.

Snoring:
A harsh sound during sleep, usually caused by a person's breathing through his mouth. Soft tissue in the roof of the mouth near the throat vibrates as air passes through. The lips, cheeks, and nostrils may also vibrate. If you sleep on your back, the mouth tends to hang open, and the tongue obstructs the air passage. Sleeping on your side may stop the snoring.

Yawn:
A deep Involuntary inhalation believed to be a response to a buildup of carbon dioxide in the Lungs. Yawning has been referred to as a socially infectious habit because of the urge to yawn if you see someone yawning.
