What are the 6 chambers of the heart?

The heart consists of four main chambers: two atria and two ventricles. The right atrium receives deoxygenated blood from the body and sends it to the right ventricle, which pumps it to the lungs for oxygenation. The left atrium receives oxygenated blood from the lungs and sends it to the left ventricle, which pumps it out to the rest of the body. While the heart has four chambers, some may refer to the atria and ventricles separately, which could lead to the mention of six distinct areas, but the heart itself is typically classified into four chambers.
