Pleural Effusion - What Is It?
During breathing activity, chest wall moves out & in, lungs expand & relax. For the smooth movement of the lungs inside the chest cavity, they are lined by pleura.
Pleura includes two thin linings, the layer lining lungs is called visceral pleura and the one lining chest wall is called parietal pleura. The cavity formed between these two layers is called Pleural cavity. It contains a small amount of lubricant called Pleural fluid which helps smooth sliding of two pleural surfaces. Any condition which results in inflammation of the pleural surfaces or accumulation of excessive fluid in the pleural cavity gives rise to symptoms attributable to pleural involvement or disease.
Pleural effusion is nothing but the collection of excess fluid in the pleural cavity. Excess fluid in the pleural space is not normal and can occur due to a variety of reasons. Depending on the chemical composition it is broadly divided into two categories, transudate and exudate.
In case you have a concern or query you can always consult a specialist & get answers to your questions!
