Surface tension from pleural fluid, positive pressure, and atmospheric pressure on the thorax.
This serosa covers the thorax cavity, the heart, and the lungs. It gives the lungs a libricant, allowing them to move easily over the thorax wall.
The diaphragm is a wall of muscle that separates the thorax and abdomen, which would place it under the lungs.
the natural tendency for the lungs to recoil and the surface tension of the alveolar fluid

Air in the chest (Thorax) causes the lung to collapse. This can be spontaneous or after chest injuries
the stomach region is called the abdomen abdominal wall..) and the upper region containing the heart and lungs is called the thorax (thoracic surgery..)
