Cardiac Cycle and Conduction

what is C

• atriole systole

• first phase of ventricular systole

• second phase of ventricular systole

• early ventricular diastole

• late ventricular diastole

in atrial systole

• atrial contracts

• bicuspid valve open

• tricuspid valve open

• blood pumped into ventricles

in first phase of ventricular systole

• ventricles contracts

• bicuspid valve closed

• tricuspid valve closed

• blood pumped out

in early phase of ventricular diastole

• ventricles relax

• bicuspid valve closed

• tricuspid valve closed

• blood flow into atria

in late phase of ventricular diastole

• ventricles relax

• bicuspid valve open

• tricuspid valve open

• blood flow passively into ventricle

• atria relax

what happen in the first and second phase of ventricular systole?

• in the first phase, the right ventricle contracts. while in the second phase, the left ventricle contracts

• in the first phase, the left ventricle contract. while in the second phase, the left ventricle contracts

• in the first phase, pressure from ventricle pumped out the blood. in the second phase, pressure from ventricle close the AV valves

• in the first phase, pressure from ventricle close the AV valves. in the second phase, pressure from ventricle pumped out the blood

the pace maker

• SA node

• AV node

• bundle of his

• purkinje fibres

Which phase of the cardiac cycle involves the CONTRACTION of the heart chambers?

• Atria

• Diastole

• Systole

• Ventricles

As the electrical impulse arrives at the Purkinje Fibers, which phase of the Cardiac Cycle occurs?

• Ventricular Diastole

• Atrial Systole

• Ventricular Systole

As the electrical signal from the SA Node travels to the AV Node, which phase of the Cardiac Cycle occurs?

• Atrial Systole

• Ventricular Systole

• Atrial Diastole
