Although ventricular pressure falls to 0 mm Hg during diastole,arterial pressure does not fall to 0 mm Hg because the next cardiac contraction refills the arteries before all the blood drains off.

During diastole, the ventricles relax and the pressure in them falls close to 0 mm Hg. However, the aortic and other arterial valves prevent blood from flowing back into the ventricles and the elastic nature of the arteries helps to maintain arterial pressure. The next cardiac contraction then refills the arteries, ensuring that arterial pressure does not fall to 0 mm Hg.
