Which chambers of the heart receive oxygenated blood?

The chambers of the heart responsible for receiving oxygenated blood are the left atrium and the right atrium. The left atrium specifically receives oxygenated blood from the lungs via the pulmonary veins, while the right atrium collects deoxygenated blood from the body through the superior and inferior vena cava, but this blood does not contain oxygen.

It is important to note that the right atrium does not receive oxygenated blood, which is why it is critical to understand its role in the circulatory system, particularly in relation to the flow of blood to and from the lungs. The left ventricle is responsible for pumping oxygenated blood out to the body, and the right ventricle pumps deoxygenated blood to the lungs. Therefore, while all the choices involve heart chambers, only the left atrium is involved in receiving oxygenated blood. The correct answer centers on the role of the atria in managing the flow of oxygenated blood from the lungs to the heart.
