What are the chambers of the heart?

The correct answer identifies all the chambers of the heart, which consist of four distinct sections: the right atrium, right ventricle, left atrium, and left ventricle. Each of these chambers plays a crucial role in the heart's function. The right atrium receives deoxygenated blood from the body through the superior and inferior vena cava and passes it to the right ventricle. The right ventricle then pumps this blood to the lungs for oxygenation.

On the other hand, the left atrium receives oxygenated blood from the lungs via the pulmonary veins and sends it to the left ventricle. The left ventricle is responsible for pumping oxygen-rich blood out to the rest of the body through the aorta. Understanding these chambers and their interconnectivity is essential for comprehending how the heart circulates blood throughout the body.

The other options mentioned either omit one or more chambers or do not accurately represent the complete structure necessary for normal heart function, thus providing an incomplete picture of the heart's anatomy.
