The left ventricle receives the clean blood from the left atrium and pumps it into the aorta, which is the largest artery in the body. The aorta then carries the blood to the rest of the body. Another difference between the atrium and ventricles is the valves they are attached to. Heart valves serve as a sort of seal, which open when blood is pumped from one area to the other and closes to prevent the blood from leaking backward.

Ventricles then pumps the blood received from atria to the body parts including lungs. â¢ Ventricles are lined up with thick walls than atria. â¢ Atria and ventricles are separated by tricuspid and bicuspid valves in the heart. â¢ Unlike in the atrial walls, Purkinje fibers (bundle of His) are found in the ventricle walls. â¢ Superior and inferior vena cava and pulmonary vein open into atria, while aorta and pulmonary artery open into ventricles.
