31
Which is a branch/terminal branch of the right coronary artery?

32
Where does the Left Marginal Artery originate from?
Left Circumflex Artery
33
Where does the Anterior Interventricular Artery originate from?
Left Coronary Artery
34
Where does the left coronary artery originate from?
Root of Aorta
35
When does the right aortic cusp fill with blood?
When Aortic pressure is greater than Ventricular pressure.
36
What muscles cause the left atrioventricular valve to close?
Papillary Muscle Contraction.
37
Which artery does the circumflex artery anastomose with?
Right Coronary Artery
38
During what stage of the cardiac cycle is the aortic valve open?
Ventricular Systole (contraction)
39
What area/structure does the right marginal artery supply?
Anterior and Inferior surface of the right ventricle.
40
What is the function of the anterior papillary muscle during ventricular systole?
Close the AV valve to prevent back-flow of blood into the atria.
41
What directly innervates the Trabeculae Carnae?
Purkinje Fibers
42
What is the function of the auricles?
Expand and increase the volume of atria to pump more blood during atrial systole.
43
Which arteries directly supply the interventricular septum?
Anterior and Posterior Interventricular Arteries
44
What is the function of Chordae Tendinae?
Anchor the leaflets of the AV valves to the papillary muscles to tightly close the valves.
45
What two structures does the Right AV Valve (tricuspid valve) seperate?
Right Atrium and Right Ventricle
46
What two chambers does the interatrial septum seperate?

49
In which chamber is the approximate position of the AV node found?
Right Atrium In the interatrial septum
50
Which chamber is the opening of the coronary sinus located in?

52
What is Sinus Venarum?
The smooth surface lining the majority of the atrium.
53
What is the embryological origin of Fossa Ovalis?

56
What vessels drain into the Right Atrium?
Inferior Vena Cava Superior Vena Cava Coronary Sinus
57
What vessels drain into the Left Atrium?
Left and Right Pulmonary Veins
58
What would happen if Cordae Tendinae was damaged?
Back-flow of blood from ventricle to atria during ventricular contraction.
59
Which two chambers does the Left AV Valve seperate?
Left Atrium and Left Ventricle
60
What is the function of the Posteromedial Papillary Muscle during ventricular systole?
Close the AV valve.
61
During what phase of the cardiac cycle does Pectinate muscle contract?
Atrial Systole

During what phase of the cardiac cycle does the Trabeculae Carneae contract?
Ventricular systole.
63
What directly innervates the Septal Papillary Muscle?
Purkinje Fibers
64
What would happen if Chordae Tendineae was damaged?
