The pleural cavity is the space between the two layers of pleura that cover the lungs and chest cavity. The pleural cavity is filled with pleural fluid, which allows the lungs to glide during breathing and protects them from mechanical damage.
Pleural fluid has low viscosity and contains proteins, electrolytes and glucose. It also contains blood clotting factors and growth factors that promote the healing of pleural damage. In addition, pleural fluid is involved in the regulation of body temperature, as it can absorb or release heat.
Normally, pleural fluid is clear and colorless, but in some diseases it may become cloudy or contain blood, pus, or other substances. This may be a sign of inflammation of the pleura (pleuritis) or other diseases of the lungs or chest cavity.
Pleural diseases can be caused by a variety of causes, including infections, tumors, trauma, allergies, and autoimmune diseases. Symptoms of pleural cavity diseases include chest pain, cough, shortness of breath, fever and other signs associated with the underlying disease.
Treatment for pleural disease may include antibiotics, antivirals, hormones, immunosuppressants, and other medications depending on the cause of the disease. In some cases, surgery may be required to remove tumors or other growths in the pleural space.
Thus, the pleural cavity plays an important role in the functioning of the lungs and chest cavity, and its diseases can lead to serious complications and even death. Therefore, it is important to monitor the health of the pleural cavity and, if necessary, consult a doctor for diagnosis and treatment.
