Aortic Valve |
Semilunar valve Location: between the left ventricle and aorta |
|
|
Atrial conducting fibers |
The specialized conduction fibers that transmit the cardiac impulse. |
|
|
Atrium |
Upper chamber of the heart. Receives blood from the veins. |
|
|
Automaticity |
The ability of cardiac cells to generate its own electrical signals independently of stimulation from the Central Nervous System. |
|
|
AV Node |
A part of cardiac conduction. System that acts as a relay station for the electrical signals coming from the SA node in the right atrium into the ventricles. |
|
|
Bicupsid Valve |
The AV valve between the left atrium and left ventricle ; also called mitral valve |
|
|
Cardiology |
The study of the heart |
|
|
Chordae Tendineae |
Tough fiberous bands of Connective Tissue that attaches the cusps of the AV valve to the walls of the heart's ventricles. |
|
|
Conduction System |
Specialized tissue in the heart that generates and transmits the electrical signals. |
|
|
Coronary Arteries |
The right and left coronary arteries which deliver oxygenated blood to the heart muscle. |

|
Electrocardiogram |
Graphic recording of the electrical events that occur during the cardiac cycle. |
|
|
Endocardium |
Inner lining of the hearts wall |
|
|
Great Vessels |
The large blood vessels that carry blood to and away from the heart. |
|
|
Heart |
The hollow muscular pump that pumps blood to the lungs for oxygenation and then to the rest of the body. |
|
|
His-Purkinje System |
A path of specialized conducting cells within the ventricles of the heart. |

|
Precordium |
Area of anterior chest that over lies the heart. |
|
|
Purkinje Fibers |
Fast conducting fibers located in the ventricular walls. |

|
SA Node |
Pacemaker of the heart |
|
|
Semilunar Valves |
A valve located between the ventricles and their attached vessels. |
|
|
Tricuspid Valve |
AV Valve found between the right atrium and right ventricle |
|
|
Ventricles |
Cavity in an organ such as the ventricles in the heart and the brain. |
