FlyingStart MEDSCI142: CVS Anatomy

Identify 2 structures which improve the efficacy of the ventricular pump

• Auricle

• Vena cava

• Atrium

• Aorta

What heart structure is NOT visible from the anterior view?

• SVC

• R ventricle

• Pulmonary arteries

• L atrium

What heart structure is VISIBLE from the posterior view?

• Arch of aorta

• Pulmonary trunk

• L auricle

• R auricle

The approximate peak pressure that is able to be generated by the right ventricle is...

• 8 mmHg

• 120 mmHg

• 5 mmHg

• 27 mmHg

The function of the papillary muscles is...

• To allow for simultaneous contraction of both ventricles

• To allow for simultaneous contraction of both atria

• To ensure the semilunar cusps stay closed during atrial systole

• The provide tension on the chordae tendineae during ventricular systole

True or false:

The peak pressure ratio between the L and R ventricle is 5:1

• True

• False

What is the outermost layer of the heart wall?

• Parietal pericardium

• Visceral pericardium

• Epicardium

• Fibrous pericardium

Which outlet/inlet has a partial fibrous skeleton around it?

• Mitral valve

• Tricuspid valve

• Pulmonary valve

• Aortic valve

What is the correct order of AP conduction in the heart?

• SA node -> AV node -> AV bundle of His -> Purkinje fibres

• SA node -> AV bundle of His -> AV node -> Purkinje Fibres

• AV node -> SA node -> SA Bundle of His -> Purkinje Fibres

• AV node -> AV internodal tracts -> SA node -> SA bundle -> Purkinje fibres

During which phase of the cardiac cycle is the mitral valve closed?

• Ventricular filling

• Ventricular ejection

• Isovolumetric ventricular contraction

• Isovolumetric ventricular relaxation
