GROSS ANATOMY

Detailed explanation-1: -The serous pericardium is a layer of serosa that lines the fibrous pericardium (parietal layer), which is reflected around the roots of the great vessels to cover the entire surface of the heart (visceral layer).

Detailed explanation-2: -The visceral serous pericardium, also known as the epicardium, covers the myocardium of the heart and can be considered its serosa. It is largely made of a mesothelium overlying some elastin-rich loose connective tissue.

Detailed explanation-3: -Visceral pericardium envelopes the heart and forms epicardium – the most superficial layer of the heart. Two layers of pericardium form the sac with the heart suspended in it by the aorta, pulmonary arteries, and pulmonary veins. Pericardial sac normally contains clear, straw-colored fluid called pericardial fluid.
