One of two membranes lining the chest cavity and covering each lung.
Pleurae, delicate membrane covering the lungs and the inner surface of the chest; it is divided into the visceral pleura, which covers the lungs, and the parietal pleura, which lines the chest wall and covers the diaphragm. Between the two layers of the pleura is a small space (pleural space) containing fluid that acts as a lubricant.
The double-walled membrane that covers the surface of the lungs and lines the wall of the chest cavity. The space between the two layers is filled with a lubricating fluid that helps the lungs move easily as they expand and contract.
The covering of the lungs (visceral pleura) and of the inner surface of the chest wall (parietal pleura). The covering consists of a closed sac of serous membrane, which has a smooth shiny moist surface due to the secretion of small amounts of fluid. This fluid lubricates the opposing visceral and parietal surfaces so that they can slide painlessly over each other during breathing.
The name of the membrane which, on either side of the chest, forms a covering for one lung. The two pleurae are distinct, though they touch one another for a short distance behind the breast-bone.
A lungs and is reflected upon the walls of the thorax and diaphragm. The pleurae are moistened with a Serous secretion that reduces friction during respiratory movements of the lungs.
A fragile membrane that envelops the lungs is known as the pleura. This membranous structure is divided into two distinct regions, which are separated by fluid. The first area is called the visceral pleura, and it covers the surface of the lungs. The second area is known as the parietal pleura, which lines the chest wall and extends to cover the diaphragm.
A delicate, dual-layered membrane consisting of an outer layer enveloping the lungs and an inner layer coating the chest cavity. Fluid present within the pleural cavity, situated between these two layers, serves as lubrication, facilitating the seamless expansion and contraction of the lungs during the breathing process.
Pleurisy, characterized by inflammation of the pleura, typically arises from a lung infection like pneumonia or tuberculosis. This condition might progress to pleural effusion, which involves the accumulation of surplus fluid between the layers of the pleura.
Pneumothorax, characterized by air presence in the pleural cavity, can lead to the collapse of a lung. This condition can manifest spontaneously or stem from a penetrating injury. Additionally, cancerous tumors might emerge within the pleura.
The membrane that covers the lungs is called the visceral pleura, while the one lining the inside of the chest is known as the parietal pleura. Together, they enclose a space termed the pleural cavity. There are two separate pleurae: one on the right and one on the left.
