It is found in the thorax, separating the lungs from its surrounding structures such as the thoracic cage and intercostal spaces, the mediastinum and the diaphragm. The pleural cavity is bounded by a double layered serous membrane called pleura.
The pleura is a thin membrane that covers each of our lungs and surrounding pulmonary cavity, and it can be subdivided into two layers, the visceral pleura which intimately adheres to the lungs, and the parietal pleura which lines the rest of the pulmonary cavity.
The left pleural cavity is similar, except that the heart, enclosed here within the pericardium, projects into it. In the living body the pleural cavity on each side is completely filled by the lung , which we’ll add to the picture.

The lung extends from the ribs in front, to the ribs behind, and from the dome of the pleural cavity, down to the diaphragm. With each breath in, and each breath out there's an increase and a decrease in the volume of the lungs. Here are the lungs by themselves, seen from in front.
The pleura consists of two layers, an inner visceral and an outer parietal layer. Both layers form a closed sac called the pleural cavity, which contains serous fluid. Due to the position of the heart, the left pleural cavity is smaller than the right.
