Answer - D - Although the right atrium receives blood with low oxygen levels from the various parts of the body, it must pass this deoxygenated blood to the right ventricle so that the blood can be pumped to the lungs. The circulation path between the heart and the lungs (and back to the heart) is referred to as pulmonary circulation. The path of blood from the heart to all of the other organs of the body is referred to as systemic circulation, which is the primary responsibility of the left ventricle.
