The ventriclesare filled with blood in two stages – diastole (heart relaxation) and atrial systole (contraction of the atria). In diastole, both the atria and the ventricles are relaxed. Blood flows from the vena cavaand pulmonary veins into the right and left atria respectively, before flowing directly into the ventricles. The … See more As contraction begins both sets of valves are closed, meaning that no blood can escape from the ventricles. Therefore, the start of systole increases the pressure within the ventricles, ready to eject blood into the aorta and … See more Once the ventricles’ pressure exceeds the pressure in the aorta/pulmonary trunk, the outflow valves(aortic/pulmonary) open, and blood is pumped from the heart into the great arteries.
