What is the outermost layer protecting the heart?

Explanation:
The outermost layer of the heart wall is the epicardium. It forms the heart’s outer surface and is the visceral layer of the serous pericardium, providing protection and helping reduce friction as the heart beats. It also contains small blood vessels and fat that supply and cushion the heart. The pericardium is a surrounding protective sac outside this layer, while the inner lining and muscular layers—endocardium and myocardium—lie inward.
