No. Most (~70%) of ventricular filling occurs passively, without atrial contraction.

Which vessel of the heart receives blood during the right ventricular systole?

Right ventricular systole is pumping blood into the PULMONARY ARTERIES just as left ventricular systole is pumping blood into the AORTA -- both at the same time.Source: http://library.med.utah.edu/kw/pharm/hyper_heart1.htmlIn right ventricular systole, the blood enters the pulmonary trunk before proceding into the pulmonary arteries.

What is the phase of ventricular contraction called?

It is called systole. This is when the ventricles contract and eject blood into the lungs (from the right ventricle) or into the systemic circulation (from left ventricle).
