Atrial and ventricular diastole

Answer 5

• both the ventricles and the atria relax

- fill with blood

Question 6

Cardiac output equation

Answer 6

Cardiac output (ml/min) = 
Stroke volume (ml) x heart rate (beats/min)

Question 7

Stroke volume

Answer 7

Volume of blood forced from ventricles with each contraction
