The four chambers of the heart are the right atrium, left atrium, left ventricle, and right ventricle. This configuration is fundamental to the heart's function, as each chamber plays a specific role in the circulatory system.

The right atrium receives deoxygenated blood from the body through the superior and inferior vena cavae and pumps it into the right ventricle, which then sends the blood to the lungs for oxygenation. The left atrium receives oxygen-rich blood from the lungs and transfers it to the left ventricle, which is responsible for pumping the oxygenated blood throughout the body. This sequential flow of blood through the four chambers efficiently supports systemic and pulmonary circulation.

The other choices contain terms that are not chambers of the heart, such as the superior and inferior vena cavae, which are the major veins returning blood to the heart, rather than being chambers themselves. Additionally, mixing the proper terms and order of the heart's anatomy in other options leads to confusion about its structure and operation. The correct answer accurately reflects the essential components of the heart's anatomy.
