Cardiac cycle

  • Cardiac cycle refers to the one cycle of contraction and relaxation of the cardiac muscles or one heartbeat.
  • A heart beat consists of contraction and relaxation of atria and ventricles. 
  • The phase of contraction is referred to as systole while the phase of relaxation is called diastole.
  • The term joint diastole is used when both atria and ventricles are undergoing relaxation or diastole together
  • During joint diastole, the blood is carried from superior and inferior vena cava into the atria and from atria to the ventricles through auriculoventricular valves
  • Blood flow is then restricted from ventricle to aorta and pulmonary trunk

As we learnt:

The total diastolic time of ventricle in cardiac cycle is 0-5 sec. Hence, the correct answer is option b.
