pleural space
Potential cavity between the visceral and parietal pleura surrounding the lungs.
Full Definition
The pleural space is the potential cavity between the visceral pleura (covering the lung surface) and the parietal pleura (lining the chest wall). Normally containing only a small amount of pleural fluid for lubrication, this space can become enlarged due to air (pneumothorax), fluid (pleural effusion), or blood (hemothorax). Understanding pleural space anatomy is crucial for chest tube placement and thoracic surgical procedures.
Usage
Usage note: Use 'pleural space' rather than 'pleural cavity' in surgical documentation.
