From the vertebral column the pleura passes to the side of the pericardium, which it covers to a slight extent; it then covers the back part of the root of the lung, from the lower border of which a triangular sheet descends vertically toward the diaphragm.
The reflection of the left pleura follows at first the ascending part of the sixth costal cartilage, and in the rest of its course is slightly lower than that of the right side.
—The arteries of the pleura are derived from the intercostal, internal mammary, musculophrenic, thymic, pericardiac, and bronchial vessels.

PLEURA [pleura], membranous lining of the upper body cavity and covering for the lungs.

 Pleural cavity - Wikipedia, the free encyclopedia
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.
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.
The parietal pleura is highly sensitive to pain; the visceral pleura is not.

 Physiological Correspondences: the Pleura
Again, the heart to contract freely and uniformly, must be maintained in the same relative position during all the changes and motions of the body; and still it must not be attached and bound except at the base, where it gives forth the arteries and veins.
And, further, the lungs must be maintained in their proper position, and not allowed in state of collapse to fall upon the heart or to suffer displacement; and in their place they must be protected from the ribs, and provided with the means of working without frictions, freely and smoothly.
From the base of the lungs the pleura is reflected upon itself, and forms two membranous bas loosely enclosing again the already encased lungs.

Tumors arising from the parietal pleura were revealed to be more difficult to resect than those from the visceral pleura because of their size and adhesion to the chest wall requiring extrapleural resection.
Fourteen tumors arose in the pleura, four in the retroperitoneum, three in the superficial soft tissue and one each in the mediastinum and uterine cervix.
