🌬️
pleura
[ˈplʊərə ]
Definition
anatomy, biology
The pleura is a thin membrane that surrounds the lungs and lines the chest cavity. It consists of two layers: the visceral pleura, which covers the lungs, and the parietal pleura, which lines the chest wall. The pleura plays an essential role in facilitating breathing by allowing the lungs to expand and contract smoothly.
Synonyms
pleural membrane.
Examples of usage
- The pleura becomes inflamed in cases of pleuritis.
- Doctors often examine the pleura in lung conditions.
- Fluid can accumulate in the pleura, leading to difficulty in breathing.
- Surgery may be needed if there are complications with the pleura.

Interesting Facts
Biology
- The pleura consists of two layers: the visceral pleura touching the lungs and the parietal pleura lining the chest wall.
- Pleural fluid, found between these layers, reduces friction and assists in smooth lung movement during breathing.
- Infections or conditions affecting the pleura can lead to pleuritis, causing sharp pain while breathing.
Medicine
- Diagnostic imaging techniques like X-rays and CT scans help identify issues with the pleura, such as fluid buildup or tumors.
- Doctors may perform a pleurodesis, a procedure to close the pleural space, to prevent recurrent pleural effusion.
- Understanding pleural health is crucial for treating respiratory diseases like pneumonia and tuberculosis.
Cultural References
- In classical anatomy, discussions of the pleura were central to the understanding of respiratory health, shaping medical practices.
- Art and literature occasionally reference the pleura as a metaphor for protection and vulnerability in the human experience.
- The study of the pleura and respiratory system has inspired various artistic representations, illustrating the beauty of human anatomy.

The word 'pleura' comes from the Greek word 'pleura,' meaning 'side' or 'rib.' This term was adopted in the medical field to describe the membrane surrounding the lungs due to its location in the thoracic cavity. Its use has been prevalent since ancient times, particularly in the study of human anatomy. Ancient Greek physicians often discussed the pleura in relation to respiratory diseases and conditions influencing breathing. Over the centuries, advancements in medical science clarified the structure and function of the pleura, making it an important focus in both anatomical studies and medical practice.
