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.
The right and left atria are the top chambers of the heart and receive blood into the heart. The right atrium receives deoxygenated blood from systemic circulation and the left atrium receives oxygenated blood from pulmonary circulation. The atria do not have inlet valves, but are separated from the ventricles by valves.
