That is a good question! You have a pleura, that surround the lungs. You have inner and outer layers (visceral and parietal layers). Both are connected to each other. In fact you have a balloon, in which your lungs grow. You take out the air from the balloon and you get the pleura. So both the come together at the blood vessels and bronchi. The lungs are totally elastic organs and collapse to small ball, if air enters the pleura. This elasticity of lungs create the negative pressure in the pleura. The negative pressure in pleura keeps the lungs in expanded condition. You have little fluid in the pleura. This reduces the friction between the outer and inner layers of pleura.
The difference between these two pleura is that the parietal pleura is the outtermost covering of the lung which is adhered to the inner thoracic wall, while the visceral pleura is the lining which is directly adhered to the lung itself. The space between these two pleuras is know as the pleual cavity.
PLEURAEach lung is enclosed in a serous pleural sac consisting two continuous membrane called visceral and parietal pleura. The two layers are continuous with each other around the hilum of the lung and enclose a potential space between them known as the pleural cavity. The pleura are lined by mesothelium. The visceral pleura invest all the surfaces of the lung forming their shiny outer surface and the parietal pleura lines the pulmonary cavities. The pleural cavity contains a layer of serous pleural fluid, which lubricates the pleural surfaces and allows the layers of pleura to slide smoothly over each other during respiration. Its surface tension also provides the cohesion that keeps the lung surface in contact with the thoracic wall.The visceral pleura or pulmonary pleura closely covers the lung and is adherent to all its surfaces, including the surfaces within the horizontal and oblique fissures. The visceral pleura dip into the lung fissures so that the lobes of the lung are also covered with it. The visceral pleura are continuous with the parietal pleura at the hilum of the lung.The parietal pleura line the pulmonary cavities. The parietal pleura consists of four parts1. Costal pleura- covers the internal surfaces of the thoracic wall.( ribs and intercostals spaces)2. Mediastinal pleura- covers the lateral aspects of the mediastinum.3. Diaphragmatic pleura- covers the superior or thoracic surface of the diaphragm on each side of the mediastinum4. Cervical pleura (pleural cupula or dome of pleura)- extends from the superior thoracic aperture into the root of the neck, forming a cup shaped pleural dome over the apex of the lung.The pleural cavity is the potential space between the layers of pleura and contains a capillary layer of serous pleural fluid, which lubricates the pleural surfaces and allows the layers of pleura to slide smoothly over each other during respiration.
Well there are two layers of membranes that line the interior of the lungs. The outer layer of the lungs is the parietal pleura and is attached to the chest wall. The visceral pleura is the inner of the two layers, and unlike the parietal pleura, the visceral pleura is not sensitive to pain. ~hope this is helpful.

The pleura are part of the respiratory system. The pleura are the membranous coverings of each lung.
The difference between these two pleura is that the parietal pleura is the outtermost covering of the lung which is adhered to the inner thoracic wall, while the visceral pleura is the lining which is directly adhered to the lung itself. The space between these two pleuras is know as the pleual cavity.

At the root of the lung, the visceral and parietal layers are continuous, forming the hilum. The parietal pleura can be further subdivided based upon its region of approximation. The cervical pleura extends into the root of the neck. The costal pleura is adjacent to the ribs and intercostal spaces
The difference between these two pleura is that the parietal pleura is the outtermost covering of the lung which is adhered to the inner thoracic wall, while the visceral pleura is the lining which is directly adhered to the lung itself.
