What is Coughing? What Causes Coughing?

What is cough?

Cough is a complex reflex event that protects the lungs against mechanical, chemical, and thermal factors and is one of the defense mechanisms of the respiratory system. Its purpose is to prevent foreign substances from entering the airways and ensure that they and the secretions in the airways are expelled. The cough reflex can be voluntary, or it can sometimes occur involuntarily. There are cough cells (receptors) in sensitive areas that cause coughing to occur. They are most commonly found in the larynx, main trachea, and large bronchi. Still, cough cells (receptors) are found in the nose, sinuses, pharynx, eardrum, external auditory canal, pericardium, and stomach. There is also a cough center in our brain near the respiratory center. Cough cells (receptors) activate this center thanks to the signals coming through the nerves, and as a result, the necessary warnings are sent to the structures that will cause the cough, again via the nerves.

There are three periods of cough:

In the first period, a deep breath is taken.

In the second period, the larynx closes, and the respiratory muscles contract against this closed larynx. During this period, which lasts for 200 milliseconds, the pressures in the lungs increase rapidly.

In the third period, the larynx suddenly opens, and the compressed air is violently expelled due to the significant pressure difference between the lungs and the outside atmosphere. The secretions and foreign substances accumulated in the respiratory tract are thrown out thanks to these rapid currents. At this time, the known 'coughing sound' is heard with the vibration of the secretions in the airways, bronchial walls, and neighboring tissues.
