Verified step by step guidance

Understand the anatomy of the heart: The heart is surrounded by layers that protect and support it. The outermost layer of the heart is called the epicardium, which is part of the serous pericardium.

Clarify the incorrect options: The epidermis is the outermost layer of the skin, not related to the heart. The peritoneum is a membrane lining the abdominal cavity and covering abdominal organs, and the periosteum is a membrane that covers bones.

Focus on the correct option: The epicardium is a thin layer of connective tissue and fat that covers the external surface of the heart. It also contains blood vessels and nerves that supply the heart.

Relate the epicardium to its function: The epicardium helps reduce friction between the heart and surrounding structures during heartbeats, as it is part of the serous membrane system.

Conclude the identification: Based on anatomical knowledge, the structure found on the surface of the heart is the epicardium, which is the correct answer.
