Pleura of the Lungs. Each lung is enclosed within a cavity that is surrounded by the pleura. The pleura (plural = pleurae) is a serous membrane that surrounds the lung. The right and left pleurae, which enclose the right and left lungs, respectively, are separated by the mediastinum.he major function of the lungs is to perform gas exchange, which requires blood from the pulmonary circulation. This blood supply contains deoxygenated blood and travels to the lungs where erythrocytes, also known as red blood cells, pick up oxygen to be transported to tissues throughout the body.
When it is inflammed, for example by infection, the condition is called 'pericarditis'. The pleura are two membranes that surround and protect the lungs. Inflammation of these structures is called 'pleuritis' or 'pleursy'. The two structures are close to eachother, so symptoms can overlap.
