The document discusses the anatomy of the pericardium. It describes the pericardium as having an outer fibrous layer and inner serous layer with sinuses. It details the attachments, structures that pierce it, and its blood supply from the internal thoracic artery and coronary arteries. Complications like pericarditis and pericardial effusion are mentioned.
