Blood will back flow

You have the atrio-ventricular valves (bicuspid & tricuspid) between your atria and ventricles. These ensure that the blood only flows in one direction; they prevent the backflow of blood into the atria.
You also have the semi-lunar valves in the pulmonary artery and aorta. These prevent the blood from flowing backwards and back into the ventricles, to make sure that the blood reaches the lungs and the rest of the body.
