Pleural Cavity is the body cavity that surrounds the right and left lung. The pleura is a serous membrane which folds back to form a two-layered, membrane structure. The thin space between the two pleural layers is known as the pleural cavity; it normally contains a small amount of pleural fluid. The outer pleura parietal pleura is attached to the chest wall. The inner pleura, visceral pleura covers the lungs and adjoining structures.

Parietal pleura is a serous membrane where?
the inner lining of the lung
What is the membrane that lines the surface of the lungs?
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.
What is the function of the pleura membrane?
Each lung is invested by an exceedingly delicate serous membrane, the pleura, which is arranged in the form of a closed invaginated sac. A portion of the serous membrane covers the surface of the lung and dips into the fissures between its lobes; it is called the pulmonary pleura (or visceral pleura).
What membrane or sac that encloses each lung is a?
The lung is enclosed by a thin memrane called pleura
What is serous membrane of the lungs?
The pleural membrane which contains fluid to prevent friction
What serous membranes would a bullet pass through if it entered the left lung?
The visceral and anterior pleural membranes. If it scarped against the heart, then it may also pass through the visceral and anterior pericardial membrane.
What is the layer of serous membrane that is firmly attached to the surface of the lung?
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.
Describe the pleural coverings of the lung and explain their purpose?
Each lung is suspended in its own pleural cavity and rests on the muscular diaphragm. The medial surface has a hilus (indentation) where the bronchi enter. Because of the shape and location of the heart, the lungs differ in size and shape. The left lung is smaller with 2 lobes, the right has 3 lobes. Lungs are mostly air spaces and connective tissue. The lung contains the air sacs where oxygen diffuses from air sacs into the blood vessels and waste carbon dioxide diffuses from the blood vessels into the air sacs. Each lung exists in a pleural cavity, a serous membrane compartment which prevents friction damage as the lungs expand and contract during breathing. The visceral pleura is the membrane fused to the outer surface of the lung; the parietal pleura is the membrane which lines the body wall. Between the two membranes in the pleural fluid.

Pleurisy is named for the pleury membrane Where is this membrane?
Lung
What is the double layered membrane surrounding each lung?
Pleura is a double layered membrane surrounding each lung.
Are the walls in our lungs similar to the walls of a ballon?
There really isn't much similarity between a balloon and a lung. The surface of a balloon is smooth...lungs have alveolar sacks that increase the surface area of the lung tissue. This also increases the cross membrane exchange from and to the lung and into the capillaries supplying oxygen and expelling carbon dioxide.
A mixture of lipoproteins is called what?
A mixture of lipoproteins is called surfactants. They acts to reduce the tendency of alveoli to collapse. Only a thin film of lubricating serous fluid separates the parietal pleura from the visceral pleura of a lung.
