Filling of ventricles with the blood takes place during:

Options:
A Ventricular diastole only
B Atrial systole only
C Ventricular and atrial systole
D Joint diastole and atrial systole

The correct answer is:
Joint diastole and atrial systole

Solution:
Joint diastole is the state when all the chambers of the heart are in a relaxed state. During this state, the bicuspid and tricuspid valves open, resulting inflow of blood from the pulmonary veins and the vena cava into the left and right ventricle respectively, from the left and right atria.
Atrial systole is a state when the atria are in a state of contraction. Due to contraction, the volume of the atria decreases, and blood starts flowing into the ventricles.
Ventricular systole is a state in which the ventricles are in a state of contraction. Thus, the volume inside the ventricles increases, and blood starts flowing into the pulmonary artery and aorta from the right and left ventricle respectively.
