*The '''Diaphragmatic''' and '''Costal Pleura''' are continuous with the Mediastinal Pleura. Together, these three membranes are the '''Parietal Pleura'''.

*Between the Parietal and Visceral Pleura is the '''Intrapleural Space''', or '''Pleural Cavity'''. This contains a small amount of serous fluid which establishes adhesion between the layers and allows smooth movement between the lung and chest wall, and between individual lobes of the [[Lungs - Anatomy & Physiology|lungs]].

*The [[Heart - Anatomy & Physiology|Heart]] is invested in a Parietal and Visceral layer of [[Structure of the Heart - Anatomy & Physiology#Pericardium|'''Pericardium''']] with the '''Pericardial Space''' separating the two membranes.

*Cranially the Costal and Mediastinal Pleura adjoin to form a 'dome' of pleura which extends cranially to the thoracic inlet. This is known as the '''Cupulae Pleurae'''. This region is only protected by soft tissue, and thus is vulnerable to injury.

*Within the pleural sac encasing the right [[Lungs - Anatomy & Physiology|lung]], there is a fold which encases the Vena Cava. It is known as the '''Plica Venae Cavae'''.
