Difference between diastole and systole

Question

What is the basic difference between diastole and systole?

Answer 1

Systole and diastole are the two phases into which the cardiac cycle is classified.

Systole is the phase when the contraction of ventricular muscle fibers takes place and the ventricles are emptied.

Diastole is the phase of the cardiac cycle whenever the ventricular muscle fibers distend and the ventricles are fully filled with blood.
