The document describes the anatomy of the heart, including the pericardial cavity between the parietal and visceral pericardium. It notes the structures of the left and right coronary arteries, atria and ventricles, with the right atrium and ventricle separated from the left by the interventricular septum. The key internal layers and valves of the heart are also outlined.
