● Protects the heart
● Anchors it to surrounding structures
, ● Prevents overfilling of the heart – if fluid builds up
in the pericardial cavity, it can
● inhibit effective pumping. (Cardiac Tamponade)
■ Serous Pericardium: (one continuous sheet with ‘2 layers’)
● Parietal Layer – Lines the internal surface of the fib
rous pericardium

○ Epicardium:
■ Visceral layer of the serous pericardium
○ Myocardium:
■ Muscle of the heart

■ Endothelium lining the chambers of the heart
■ Prevents clotting of blood within the heart
