parietal pleura

The serous membrane that lines the chest cavity; it extends from the mediastinal roots of the lungs and covers the sides of the pericardium to the chest wall and backward to the spine. The visceral and parietal pleural layers are separated only by a lubricating secretion. These layers may become adherent or separated by air or by blood, pus, or other fluids, when the lungs or chest wall are injured or inflamed.
