Anatomy of a cough

Nerve endings abound in the lining of our respiratory tract, from the back of our throat to the depths of our lungs. When they are inflamed, nerve impulses are sent to the brain’s cough center, activating a series of coordinated muscle activities that result in a cough. This is referred to as the cough reflex.

The cough initially starts with a gasp pulling a deep breath into the lungs. The glottis then snaps shut, covering the trachea or windpipe. The third stage is the forceful contraction of the muscles of the chest, abdomen, and diaphragm. These muscles softly push air from the lungs up via the nose and mouth during normal breathing. When the glottis is closed, the air cannot escape, causing considerable pressure to build up in the airways. Finally, the glottis opens, and air rushes out. With a vigorous cough, the air escapes at nearly the speed of sound, producing the barking or whooping sound we call a cough.

Knowing your cough

What really is that nagging cough, and how can you diagnose it? Cough for a minute or two, and you could worry something has gone down the wrong pipe. If you cough for a few days, you might believe you have caught a cold or the flu. During the first week, allergies or bronchitis may come to mind. However, after three or four weeks, your mind begins to race, and your anxiety begins to grow.

If a doctor determines that a cough is the result of a typical cold or flu, the common suggestion is to rest, drink lots of fluids, and let it run its course. Coughs of this type usually go away after 12 weeks.

A cough produced by a viral illness lasting more than a couple of weeks would almost certainly necessitate medical care. A chest X-ray may be ordered by the doctor, and a sample of phlegm may be submitted to a laboratory for investigation to discover what is causing the illness.

The patient may be asked to breathe in and out of a tube connected to a machine, which allows the doctor to evaluate whether the airways are blocked (this test is known as spirometry), which is prevalent in asthma or emphysema. If the patient is diagnosed with asthma, he/she may be prescribed asthma medication. A doctor may occasionally recommend a patient to a lung, ear, nose, and throat specialist (ENT).

Key facts you should know

Coughing is a natural and necessary reflex that protects your airway and lungs from irritants, germs, mucus, and dust.
Coughing can send air and particles out of your lungs and throat at speeds approaching 50 miles per hour.
Some pathogens use coughing to transmit to new hosts.
Coughs can be caused by a variety of factors.
A cough that does not go away or is accompanied by other symptoms such as shortness of breath, mucus production, or bloody phlegm may indicate a more serious medical problem. A doctor is required for an uncommon and prolonged cough.
Some coughs only tend to occur at night.

Phases of Cough

Inhalation Phase
01

Inhalation Phase

The inhalation of air into the lungs causes the expiratory muscles to lengthen (2.5 – 3.0 liters)
Compressive Phase
02

Compressive Phase

As a result of expiratory muscle contraction, the glottis closes, and intrathoracic pressure rises.
Expiratory phase
03

Expiratory phase

Excessive expiratory flow and loud coughs result from the glottis opening. A burst of high-velocity air is released.

Who is more prone to have a cough?

A cough can affect everyone. The most prevalent symptom reported in healthcare providers offices is a cough. Some people, however, are more prone to coughing than others. These include who:

Getting immunized against influenza, COVID-19, and pneumonia.
