<unk> s a sudden, often repetitive, spasmodic contraction of the thoracic cavity, resulting in a violent release of air from the lungs, and usually accompanied by a distinctive sound. A<unk> y itself is not a complete diagnosis but rather a symptom of an underlying condition, despite this, it accounts as one of the most common indications for visits to the general practitioners and family physicians with a good proportion of these cases resulting in a pulmonology referral.<unk> ing is an action the body takes to get rid of substances that are irritating the air passages. The act of<unk> ing can be triggered by a myriad of conditions physiologic and otherwise. A<unk> s mostly initiated to clear a buildup of phlegm within the trachea.<unk> ing can also be triggered by a bolus of food entering the trachea and other parts of the respiratory tree rather than the esophagus due to a failure of the epiglottis function.
