Parts of Pleura• A- Visceral Pleura: That covers the lungs.• B- Parietal Pleura: That lines the

surroundings. It is divided into:1- Cervical.2- Costal.3- Mediastinal.4- Diaphragmatic.

Applied Anatomy• 1- Pneumothorax: Air in pleural sac

(accidental or induced).• 2- Haemothorax: blood in pleural sac.• 3- Empyema: pus in the pleural sac.• 4- In kidney operations avoid injury of

pleura.
