There are a couple of primary differences between the atria and ventricles. The heart has four chambers. Atria make up the top chambers of the heart whereas ventricles make up the bottom chambers. This means that there are atrium and ventricle on both, right and left sides of the heart. The right part of the heart receives unoxygenized (impure) blood and sends it from ventricles to the atria.
(Read more: Difference Between Left and Right Ventricle) What is the difference between Atria and Ventricles? â¢ Atria are situated at the top of the heart, whereas ventricles are at the bottom. â¢ Atria are quite smaller than ventricles. â¢ Atria receive blood from body parts and lungs and pass the blood to ventricles. 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.
