*The Heart is invested in a Parietal and Visceral layer of '''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 lung, there is a fold which encases the Vena Cava. It is known as the '''Plica Venae Cavae'''.
*The Pleural Membranes are larger than the lungs which they encase, thus there are areas where the facing surfaces of parietal pleura touch eachother. These are known as '''Pleural Recesses'''. One example is the '''Costodiaphragmatic Recess''', the space between the costal and diaphragmatic pleura. The volume of the recess varies to a point due to the phase of inspiration/expiration.

*In '''Cattle''' the Mediastinum is a tough membrane, in contrast to '''Horses''' where it is rather thin and more delicate.
