Within the mediastinum the heart is separated from the other mediastinal structures by a tough membrane known as the pericardium or pericardial sac and sits in its own space called the pericardial cavity. The lungs are covered by a thin tissue layer called the pleura.

The impressions of these structures can be seen on the medial lung surface. The left lung is slightly smaller than the right this is due to the presence of the heart. The human heart is located within the thoracic cavity medially between the lungs in the space known as the mediastinum.
