The four chambers of the heart consist of the right atrium, right ventricle, left atrium, and left ventricle. This configuration is crucial to the heart's function, as it allows for the separation of oxygenated and deoxygenated blood and facilitates efficient circulation.

The right atrium receives deoxygenated blood from the body through the superior and inferior vena cavae. This blood is then pumped into the right ventricle, which sends it to the lungs via the pulmonary arteries for oxygenation. Once the blood is oxygen-rich, it returns to the left atrium through the pulmonary veins. The left atrium then contracts to push this oxygenated blood into the left ventricle, which is responsible for pumping it out to the rest of the body through the aorta.

Understanding this arrangement is essential for comprehending how blood circulates through the body, highlighting the heart's role in maintaining systemic and pulmonary circulation efficiently. Each chamber plays a distinct role in the overall process, and their proper functioning is critical for sustaining life.
