surface tension.
The two pleural membranes are the visceral pleura and the parietal pleura. The visceral pleura is the innermost layer that covers the surface of the lungs, while the parietal pleura lines the chest cavity. These membranes create a fluid-filled space called the pleural cavity, which helps to reduce friction and allows for smooth movement of the lungs during breathing.
The pleural cavity is located in between the visceral and parietal of the lungs.
The lungs are surrounded by two membranes, the pleurae. The outer pleura is attached to the chest wall and is known as the Parietal pleura; the inner one is attached to the lung and other visceral tissues and is known as the Visceral pleura. In between the two is a thin space known as the pleural cavity or pleural space. It is filled with pleural fluid, a serous fluid produced by the pleura.
Visceral pleura
The pleural cavity is the potential space between the two pleura (visceral and parietal) of the lungs, the intraembryonic coelom is one continuous space. During development this space partitions to form the pericardial, pleural and peritoneal cavities. The diaphragm and the paired pleuropericardial membranes separate the coelomic cavity into four parts. From the splanchnopleura (the visceral mesodermal layer) develops the Visceral pleura and from the somatopleura (parietal mesodermal layer) develops the parietal pleura.

Pleura covers the lungs. It has 2 folds- the visceral (inner) pleura and the parietal (outer) 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.
They are called pleura. There are 2 membranes, the visceral which is the outer slippery covering, and the parietal which is the inner covering, with a cavity in between them called the pleural cavity
The visceral and anterior pleural membranes. If it scarped against the heart, then it may also pass through the visceral and anterior pericardial membrane.
the membrane on the surface of the lung is called the parietal pleura, but the membrance that lines the lungs themselves are called the visceral pleura.
