[citation needed] Bed rest interferes with the expansion of the chest and limits the amount of air that can be taken into the lungs in preparation for coughing, making the cough weak and ineffective. [ citation needed ] This reflex may also be impaired by damage to the internal branch of the superior laryngeal nerve which relays the afferent ...
A cough is a sudden expulsion of air through the large breathing passages which can help clear them of fluids, irritants, foreign particles and microbes.As a protective reflex, coughing can be repetitive with the cough reflex following three phases: an inhalation, a forced exhalation against a closed glottis, and a violent release of air from the lungs following opening of the glottis, usually ...
This explains why coughing often occurs in those who smoke cigarettes. The body's natural reaction is to increase mucus production. In addition, mucus aids in moisturizing the inhaled air and prevents tissues such as the nasal and airway epithelia from drying out. [11] Mucus is produced continuously in the respiratory tract. Mucociliary action ...

Doctors sound off on the causes of a cough that won't go away and what to do about it.
A rise in the arterial partial pressure of CO 2 and, to a lesser extent, a fall in the arterial partial pressure of O 2, will reflexly cause deeper and faster breathing until the blood gas tensions in the lungs, and therefore the arterial blood, return to normal. The converse happens when the carbon dioxide tension falls, or, again to a lesser ...
