Coughing

Description

You cough at a speed of 100 miles per hour when clearing your breathing passages of unwanted irritants. First, your vocal cords open widely, allowing a large amount of air to be sucked into your lungs. Your epiglottis closes off your trachea, and your diaphragm and rib muscles contract. With the increased pressure behind it, the air is forcefully expelled, creating a rushing sound as it moves quickly past your vocal cords. The air dislodges the irritant, making it possible for you to breathe comfortably again.
