THORAX ABDOMEN AND PELVIS

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 pericardium, also called pericardial sac, is a double-walled sac containing the heart and the roots of the great vessels. It has two layers, an outer layer made of strong inelastic connective tissue (fibrous pericardium), and an inner layer made of serous membrane (serous pericardium).

Detailed explanation-3: -The outer layer of the pericardium, which is a thin sac of tissue that surrounds the heart.

Detailed explanation-4: -The serous pericardium forms a closed sac surrounding the heart and the roots of the great vessels. The epicardium (also known as visceral pericardium), the outermost layer of the heart, is continuous at the cardiac base with the parietal pericardium. The parietal pericardium is fused with the fibrous pericardium.
