The layer that directly covers the heart is the visceral pericardium, also known as the epicardium. It is the inner layer of the serous pericardium and lies in direct contact with the myocardium, tightly following the heart’s contours. The serous pericardium is made up of two layers: the visceral layer (covering the heart) and the parietal layer (lining the fibrous pericardium). The fibrous pericardium is the tough outer sac that anchors the heart in place. The space between the visceral and parietal serous layers is the pericardial cavity, containing a small amount of serous fluid to reduce friction during heartbeats.
