Moist membrane covering the lung and chest cavity wall on each side?
607159
there are two types of pleural membranes:\nvisceral pleura adheres close to the actual lung tissue itself.\nparietal pleura lines the chest cavity.\n\nBoth of these are serous membranes and secrete mucus so when you breathe,the two slippery mbns can rub without friction.  If you have a sucking chest wound and air gets in, it dries these two mbns and makes them sticky-friction and then we aren't able to breathe so well. It needs to be nice and slimey between the two pleural mbns.

Go to the doctor as soon as possible\nPains in the chest could be from a virus or pneumonia

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.\n\nThe pleural fluid lubricates the pleural surfaces and allows the layers of pleura to slide against each other easily during respiration. It also provides the surface tension that keeps the lung surface in contact with the chest wall. During quiet breathing, the cavity normally experiences a negative pressure (compared to the atmosphere) which helps adhere the lungs to the chest wall, so that movements of the chest wall during breathing are coupled closely to movements of the lungs.\n\nThe parietal pleura is highly sensitive to pain; the visceral pleura is not. The visceral pleura has a dual blood supply, from the bronchial and pulmonary arteries. In humans, there is no anatomical connection between the left and right pleural cavities, so in cases of pneumothorax (see below), the other hemithorax will still be able to function normally.\n\nDiseases involving the pleura include:\n\n    * Pneumothorax (collapsed lung): air enters the pleural cavity, either from the outside or from the lungs. This can be the result of a penetrating chest wound, or of an internal injury. A tension pneumothorax is where the punctured chest wall forms a one way valve so that air may enter (through the puncture) on inspiration, but cannot exit on expiration. With each breath air builds up in the chest cavity, compressing the lung still further, thus reducing the surface area available for gas exchange. It is a medical emergency.\n    * Pleural effusion: fluid accumulates in the pleural space, compressing the lungs. This can result for example from lung cancer, infection or heart failure.\n    * Mesothelioma: this is a type of cancer caused by asbestos exposure.\n    * Pleurisy: an inflammation of the pleura, especially one causing painful respiration. Pleurisy can be provoked by a variety of infectious and non-infectious causes. The modern term for this is pleuritis, but the older term is still in common use.

Consolidation is when an area of lung is full of infection and white blood cells go to that area to fight infection as in pneumonia or abscess. A collapsed lung--the lung tissue is surrounded by a sac--the sack has a leak-called pneumothorax--very serious,may need a chest tube inserted to re inflate lung--can happen from accident,disease, surgery, or "spontaneous from lung wall weakness

Gee...broad question...depends what ur transporting.\ne.g. for gases u need a semi-permeable membrane, a thin membrane, a gradient, a moist/mucus surface

you should go see a doc\nit could be pleurisy which is an inflammation of the pleural or lung lining get it checked out

B\nThe visceral peritoneum covering the stomach extends on both sides into large, double-layered sheets that are filled with prominent patches of fat, giving it a lace-like appearance.

outer three coverings are renal fascia(outermost fibrous membrane), adipose capsule(middle fatty layer which absorbs shock), renal capsule(inner fibrous layer).\nlearn it as F.A.C and F is farthermost and C as closest(and pronunce as f**k)

The wall of alveoli consist of two types pf alveolar epithelial cells.The more numerous type 1 alveolar cells are simple squamous epithelial cells that form a nearly continous lining of the alveolar wall.Type 2 alveolar cells also called septal cells are fewer in number and found between type1 alveolar cells.The thin type1 alveolar cells are the main sites of gas exchange.Type 2 alveolar cells rounded or cuboidal epithelial cells with free surfaces containing microvilli,secrete alveolar fluid which keeps the surface between the cells  and the air moist.\n\nWell,since you didnt asked for more detail, this is the most simple answer that i can gave you.Hope this help ya.

What is Pleurisy?\n\nPleurisy is an inflammation of the pleura. There are two pleurae, one around each lung. The pleura is a two-ply membrane that both encloses the lung and lines the chest cavity. \n\nThis two-layer protective wrapping fits closely around the lung, with, normally, no actual space between the inner and outer layers. The layers are joined at the edges, so that the pleura might be compared to a closed balloon, completely empty of air and wrapped tightly around the outside of each of the lungs. \n\nOnly a thin Iubricating layer of fluid is between the inner pleural lining and the outer one. Ordinarily, the smooth linings and lubricating fluid serve to allow the lung free movement within the chest for normal breathing. The almost non-existent space occupied by the lubricant can develop into what is called a pleural cavity if its fluid contents increase.

May be your pleural covering of your lung on the right side is affected mildly.

The diffusion of gas across a membrane requires that the membrane be wet.  If the wet membrane were on the surface the animal would quickly dry out.  Since the exchange is located deep in a lung there is opportunity for the water to be recovered before exhaling.

Could be Bronchitis, maybe Pleurisy. You could go to your doc and get a chest xray. This will show any fluids, and enlargements, however pleurisy will not show on an xray. Your doc can tell if you have pleurisy by listening to your lungs. Pleurisy usually is a one sided pain though. Sounds like some kind a respiratory infection. Good Luck!
