Question

give the effect of ventricular systole on the blood flow

Answer 1

When blood vessels dilate, the blood flow is increased due to a decrease in vascular resistance. Therefore, dilation of arteries and arterioles leads to an immediate decrease in arterial blood pressure and heart rate. Cardiac output is the amount of blood ejected by the left ventricle in one minute.
