What is pleurisy and how is pleurisy related to the pleura in the lungs?
Pleurisy is also known as pleuritis which is the inflammation of the pleural.
The smooth movement of the parietal pleural over the visceral pleural is during inspiration and expiration is impaired or obstructed when the pleural surfaces become damaged and roughened particularly due to bacterial infections. This produces the symptom called pleurisy, a severe stabbing feeling on the chest wall during inspiration and expiration.
Damage to the pleural linings may result in fibrous scar formation leading to the inability of the two pleura to slide over one another in a proper manner.
The result of this is that some of the lymphatics draining the lungs and its pleura deposit their content in the fibrous septa formed in between the pleura. These lymphatics can also dislodge large quantities of fluid into the pleural cavity leading to pleural effusion.
Unfortunately,these lymphatics can also carry with them bacteria and tumour cells into the pleural cavity thereby producing infected pleural effusion and malignant pleural effusion respectively.
