Question

Quizplus · Accepted Answer

The blood pressure in the large systemic arteries is greatest during ventricular systole. This is when the ventricles of the heart contract, pushing blood out into the arteries with the greatest force, resulting in the highest pressure in the arteries. During ventricular diastole, the pressure in the arteries decreases as the ventricles relax and refill with blood. Atrial systole and diastole relate to the contraction and relaxation of the atria and do not have as great an impact on blood pressure in the systemic arteries.
