Why does the surface of the lungs need to be covered with pleura?
In human anatomy, the pleural cavity is the thin fluid-filled space between the two pulmonary pleurae (visceral and parietal) of each lung.A pleura is a serous membrane which folds back onto itself to form a two-layered membranous pleural sac.leural fluid is a serous fluid produced by the serous membrane covering normal pleurae. Most fluid is produced by the parietal circulation (intercostal arteries) via bulk flow and reabsorbed by the lymphatic system. The lungs are surrounded by a double membrane called pleura. This membrane has two layers, a parietal pleura and a visceral pleura. The parietal pleura is attached to the chest wall and the visceral pleura covers the surface of the lungs.Between these layers of pleura is a potential space i.e. a space that doesn’t exist but it could exist if something goes wrong.his membrane has two layers, a parietal pleura and a visceral pleura. The parietal pleura is attached to the chest wall and the visceral pleura covers the surface of the lungs. The pulmonary pleurae are the two pleurae of the invaginated sac surrounding each lung and attaching to the thoracic cavity. The visceral pleura is the delicate serous membrane that covers the surface of each lung and dips into the fissures between the lobes.The parietal pleura is the outer membrane which is attached to the inner surface of the thoracic cavity. It also separates the pleural cavity from the mediastinum.tructure [edit]. The visceral pleura is a delicate serous membrane that closely covers the surfaces of the lungs and dips into the fissures that separate the lobes. Causes of Pleural Effusions. The pleura is a thin membrane that lines the surface of the lungs and the inside of the chest wall outside the lungs. In pleural effusions, fluid accumulates in the space between the layers of pleura.he pleura is a thin membrane that lines the surface of the lungs and the inside of the chest wall outside the lungs. In pleural effusions, fluid accumulates in the space between the layers of pleura. The pleural membrane is thin, moist, slippery and has two layers. The outer, or parietal, pleura lines the inside of the rib cage and the diaphragm while the inner, visceral or pulmonary, layer covers the lungs. Between the two layers is the intrapleural space, which normally contains fluid secreted by the membranes.his article, the third in a four-part series on the respiratory system, looks at the lungs, pleura and respiratory defence mechanisms. The lungs. The lungs are cone-shaped organs that sit in the chest cavity, protected by the ribs. Pleura of the Lungs. The pleura includes two thin layers of tissue that protect and cushion the lungs. The inner layer (visceral pleura) wraps around the lungs and is stuck so tightly to the lungs that it cannot be peeled off. The outer layer (parietal pleura) lines the inside of the chest wall.The very thin space between the layers is called the pleural cavity. A liquid, called pleural fluid, lubricates the pleural cavity so that the two layers of pleural tissue can slide against each other.By Healthwise Staff.he outer layer (parietal pleura) lines the inside of the chest wall. The very thin space between the layers is called the pleural cavity. A liquid, called pleural fluid, lubricates the pleural cavity so that the two layers of pleural tissue can slide against each other. By Healthwise Staff. The two lungs and their pleural sacs are situated in the thoracic cavity (figs. 22-1 and 22-2). The pleura is a thin, glistening, slippery serous membrane, inflammation of which is called pleurisy. The pleura lines the thoracic wall and diaphragm, where it is known as the parietal pleura.It is reflected onto the lung, where it is called the visceral pleura.2-1 and 22-2).

Pleural mesothelioma is a disease that affects the lining of the lungs, or lung pleura. Sometimes doctors refer to this disease as mesothelioma of the pleura. It is a common misconception that mesothelioma is a type of primary lung cancer; it is not.Mesothelioma is a cancer of the serous membranes. These membranes enclose a number of organs throughout the midsection of the body, including the lungs.ometimes doctors refer to this disease as mesothelioma of the pleura.
