A thin membrane which lines the inside of the chest cavity and also covers the lungs. The two ‘pleural cavities’ are enclosed compartments, with normally only a film of fluid between the layer lining the chest (parietal pleura) and the layer covering the lungs (visceral pleura). The two layers continually tend to pull away from each other, because of the stretched elastic condition of the lungs — an important factor in the mechanics of breathing. If the chest wall is penetrated by a wound, air is readily sucked into the pleural cavity, separating the two pleural layers and collapsing the lung.

— Stuart Judge

See breathing; lungs.

n

A delicate serous membrane enclosing the lung, composed of a single layer of flattened mesothelial cells resting on a delicate membrane of connective tissue.

A thin two-layered membrane that secretes fluid, and lines the thoracic wall (parietal pleura), the diaphragm (diaphragmatic pleura), and the lungs (visceral pleura).

Pleura

 
pleura (plʊr'ə), membranous lining of the upper body cavity and covering for the lungs. The pleura is a two-layered structure: the parietal pleura lines the walls of the chest cage and covers the upper surface of the diaphragm, and the pulmonary pleura, or visceral layer, tightly covers the surface of the lungs. The two layers, which are in fact one continuous sheet of tissue, are generally connected to each other. In humans, the pleural cavity is further separated into left and right sides by the heart and pericardial cavity. There is normally a slight amount of watery fluid within the pleural cavity that lubricates the pleural surfaces and allows the lungs to slide freely over the inner surface of the thoracic wall during breathing. When a lung collapses or develops an infection, a condition known as pleurisy can develop. The pleura becomes inflamed, and the pleural cavity becomes noticeably larger. Pleurisy can be extremely painful, but can be medically eradicated in many cases. Mesothelioma is a tumor of the pleura seen most frequently in asbestos workers.


Pl. pleurae [Gr.] the serous membrane investing the lungs (pulmonary pleura) and lining the walls of the thoracic cavity (parietal pleura), the two layers enclosing a potential space, the pleural cavity.
