Methods The morphosis of the mesothelium of the parietal pleura in rat were investigated by intrapleura injection with tracers and observed by scanning electron microscope.
The pleural cavity or pleural space lies between the parietal pleura which is stuck to the chest wall and the visceral pleura which is stuck to the lungs.
The visceral or pulmonary pleura covers the outside of the lungs, and the parietal or costal pleura lines the inside of the chest wall, and it extends over the top of diaphragm.
