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.
-In the heart there are 2 atria & 2 ventricles. -The right atrium takes in the blood without oxygen and sends it to the right ventricle. - The right ventricle sends the blood with no oxygen in it to the lungs. -The left atrium takes in blood with oxygen from the lungs & then sends it to left ventricle.
