The pleural membranes cover which system?

The pleural membranes are essential components of the respiratory system, playing a critical role in lung function. These membranes consist of two layers: the visceral pleura, which directly covers the lungs, and the parietal pleura, which lines the chest wall. This structure helps to create a pleural cavity filled with pleural fluid that provides lubrication, allowing the lungs to expand and contract smoothly during the process of breathing. By reducing friction, the pleural membranes ensure efficient respiratory mechanics and protect lung tissue from potential injury.

Understanding the role of the pleural membranes is vital for anyone working in healthcare, particularly in respiratory health, as they are fundamental to normal pulmonary function.
