Cardiac Cycle

Question 1

Three phases of the Cardiac Cycle

Answer 1

Ventricular Filling

Ventricular Contraction

Early Diastole

Question 2

Ventricular Filling

Answer 2

AV valves open and blood is poured into ventricles; heart relaxed

Question 3

Atrial Contraction

Answer 3

Blood poured into ventricles

SA node > AV node

Question 4

Isovolumetric Contraction

Answer 4

Valves close; upward pressure

AV node > bundle of his > L & R bundle branches

Question 5

Ventricular Ejection

Answer 5

Semilunar valve opens > blood leaves

L & R bundle branches > purkinje fibers

Question 6

Isovolumentric Relaxation

Answer 6

Valves close

Question 7

Phases A-E of Cardiac Cycle

Answer 7

Ventricular Filling > Atrial Contraction > Isovolumetric Contraction > Ventricular Ejection > Isovolumetric Relaxation
