Study Notes
Coverings of the Heart
- The heart is enclosed in a double-walled sac called the pericardium
- The superficial part is the fibrous pericardium; a tough, dense connective tissue layer.
- It protects the heart, anchors it to surrounding structures, and prevents overfilling.
- Deep to the fibrous pericardium is a thin, slippery two-layered serous pericardium.
- The parietal layer lines the internal surface of the fibrous pericardium.
- The visceral layer, or epicardium, is an integral part of the heart wall that continues over the external heart surface.
- A slit-like pericardial cavity between these layers contains serous fluid.
- The fluid allows for smooth, friction-free movement during heart activity.
