Definitions:

Pericardial Sac

The Pericardial Sac, or pericardium, is a double-layered membrane that surrounds the heart, providing it with protection and lubrication.

Papillary Muscles

Muscles located in the ventricles of the heart, attaching to the cusps of the atrioventricular valves via chordae tendineae and preventing valve inversion.

AV Valves

The atrioventricular valves, consisting of the tricuspid and mitral valves, are located between the atria and ventricles in the heart, regulating blood flow and preventing backflow.

Semilunar Valves

Heart valves located at the bases of the aorta and the pulmonary artery that prevent backflow of blood into the ventricles during systole by opening to allow blood ejection and closing during diastole.
