Coughs

Coughs Overview

A cough is an action the body takes to get rid of substances that are irritating to the air passages, which carry the air a person breathes in from the nose and mouth to the lungs. A cough occurs when cells along the air passages get irritated and trigger a chain of events. The result is air in the lungs is forced out under high pressure. A person can choose to cough (a voluntary process), or the body may cough on its own (an involuntary process).
