Pleura<br />
• Meso<strong>the</strong>lial lining <strong>of</strong><br />
each hemithorax<br />
Derived from<br />
embryonic coelomic<br />
lining<br />
Visceral pleura: lung<br />
Parietal pleura: wall<br />
Costal<br />
Diaphragmatic<br />
Mediastinal<br />
Cervical<br />
<strong>Pleural</strong> <strong>Cavity</strong><br />
Potential space between visceral & parietal pleura<br />
Capillary layer <strong>of</strong> serous fluid produced by meso<strong>the</strong>lium<br />
Reduces friction<br />
Surface tension provides cohesion between lung and thoracic wall
