The skin on the heart is called the pericardium. It is a double-walled sac that surrounds and protects the heart, consisting of an outer fibrous layer and an inner serous layer. The serous layer is further divided into the parietal and visceral pericardium, with the visceral layer also known as the epicardium, which is the outer layer of the heart itself. This structure helps reduce friction as the heart beats.
