THORAX ABDOMEN AND PELVIS

Detailed explanation-1: -The pericardium is the fibrous sac that surrounds the heart. It can be divided into three layers, the fibrous pericardium, the parietal pericardium, and the visceral pericardium. The parietal and visceral pericardia together form the serous pericardium.

Detailed explanation-2: -The two layers of serous pericardium: visceral and parietal are separated by the pericardial cavity, which contains 20 to 60 mL of the plasma ultrafiltrate. The pericardium acts as mechanical protection for the heart and big vessels, and a lubrication to reduce friction between the heart and the surrounding structures.

Detailed explanation-3: -Fibrous pericardium: This is the tough, outermost layer of your pericardium. It’s made of connective tissue that prevents your heart from expanding too much.

Detailed explanation-4: -The pericardium, which translates as “around the heart, ‘’ is a double-layered connective tissue membrane that surrounds the heart like a sac and, therefore, is also called as a pericardial sac (Fig. 1.2).
