Which of the following correctly identifies the relationship between the heart's chambers and blood circulation?

The relationship between the heart's chambers and blood circulation is accurately described by the statement that the atria receive blood while the ventricles pump blood. The heart consists of four chambers: two atria (the upper chambers) and two ventricles (the lower chambers). Blood enters the heart through the atria. The right atrium receives deoxygenated blood returning from the body, while the left atrium receives oxygenated blood from the lungs. Once the atria fill with blood, they contract to push this blood into the ventricles.

After filling, the ventricles contract to pump blood out of the heart. The right ventricle sends deoxygenated blood to the lungs for oxygenation, while the left ventricle pumps oxygenated blood to the rest of the body. This distinct flow pattern is crucial for maintaining efficient circulation and ensuring that oxygen-rich and oxygen-poor blood are properly managed.

The other options inaccurately depict the roles of the heart's chambers, creating confusion about the functions of the atria and ventricles.
