The serous membrane that covers the surface of the lung is the visceral pleura and is separated from the outer membrane, the parietal pleura, by just the film of pleural fluid in the pleural cavity. The visceral pleura follows the fissures of the lung and the root of the lung structures. The parietal pleura is attached to the mediastinum, the ...
The fissures are double folds of pleura that section the lungs and help in their expansion, [6] allowing the lung to ventilate more effectively even if parts of it (usually the basal segments) fail to expand properly due to congestion or consolidation.The function of the visceral pleura is to produce and reabsorb fluid.

The pleura is the serous membrane that surrounds the lungs in the pleural cavity; The peritoneum is the serous membrane that surrounds several organs in the abdominopelvic cavity. The tunica vaginalis is the serous membrane, which surrounds the male gonad, the testis. The two layers of serous membranes are named parietal and visceral.
The lungs are the largest organs in the lower respiratory tract. The lungs are suspended within the pleural cavity of the thorax. The pleurae are two thin membranes, one cell layer thick, which surround the lungs. The inner (visceral pleura) covers the lungs and the outer (parietal pleura) lines the inner surface of the chest wall. This ...
The rib cage is separated from the lung by a two-layered membranous coating, the pleura. The hilum is the large triangular depression where the connection between the parietal pleura (covering the rib cage) and the visceral pleura (covering the lung) is made, and this marks the meeting point between the mediastinum and the pleural cavities.
With pleural effusion, fluid often builds up in the costophrenic angle (due to gravity). This can push the lung upwards, resulting in "blunting" of the costophrenic angle. The posterior angle is the deepest. Obtuse angulation is sign of disease. Chest x-ray is the first test done to confirm an excess of pleural fluid.
It folds back to form two layers, and each layer is called parietal pleura and visceral pleura. The pleural cavity refers to the area between the parietal and visceral pleura, and pleural fluid fills the pleural cavity to lubricate the pleural surface and provide surface tension. These functions ensure the safety of the lungs and proper ...
It innervates the bronchial tree and the visceral pleura.According to the relation of nerves to the root of the lung, the pulmonary plexus is divided into the anterior pulmonary plexus, which lies in front of the lung and the posterior pulmonary plexus, which lies behind the lung.
