Visceral Pleura Function It forms part of the pleural sac, working alongside the parietal pleura (which lines the thoracic cavity) to create the pleural cavity. the visceral pleura plays a crucial role in facilitating lung movement, reducing friction, and maintaining negative intrathoracic pressure necessary for breathing. The visceral pleura covers the outer surface of the lungs, and extends into the interlobar fissures. it is continuous with the parietal pleura at the hilum of each lung (this is where structures enter and leave the lung).
Visceral Pleura Anatomy Britannica The term pleura encompasses the parietal pleura (lining the inner surface of the chest wall), the visceral pleura (lining the outer surface of the lung and invaginating into the lung in the form of fissures), and the intervening pleural space. What are the parts of the pleura? a hollow area (pleural space) lies between the layers of your pleura. your pleural space contains a thin layer of pleural fluid. pleural fluid helps your pleura move as you breathe. the pleura has two layers: visceral pleura. this is the inner layer of your pleura. it covers your lungs, blood vessels, bronchi. The visceral pleura is a thin, protective membrane that directly covers the surface of each lung, extending into the deep folds that divide the lung lobes. it works with another layer to provide a lubricated surface, facilitating smooth lung expansion and contraction during respiration. Within the pleural cavity, a thin layer of fluid is produced by the serous epithelial membrane lining the visceral and parietal pleurae. in addition, the visceral pleura invests all surfaces of the lung and gives the lung a shiny appearance.

Within the pleural cavity, a thin layer of fluid is produced by the serous epithelial membrane lining the visceral and parietal pleurae. in addition, the visceral pleura invests all surfaces of the lung and gives the lung a shiny appearance. A portion of the serous membrane covers the surface of the lung and dips into the fissures between its lobes; it is called the visceral pleura or pulmonary pleura. There are two types of pleura; parietal and visceral. the parietal pleura is the thicker and more durable outer layer that lines the inner aspect of the thoracic cavity and the mediastinum. the visceral pleura is the more delicate inner layer of pleura that lines the outer surface of the lung itself. The visceral pleura helps maintain negative pressure within the pleural cavity, which is critical for lung inflation. the pressure difference between the pleural cavity and the atmosphere allows air to enter the lungs during inhalation. As the visceral pleura completely envelops the lungs, it also extends into and covers the fissures between the lobes. in the right lung, it lines both the major (oblique) and minor (horizontal) fissures, while in the left lung, it covers the major fissure.
