Which heart chambers serve as receiving centers for blood?

• A. Atria
• B. Ventricles
• C. Aorta
• D. Pulmonary trunk

Answer: (A)

The receiving chambers are the atria. They collect blood returning to the heart from the body and lungs: the right atrium receives systemic venous return via the superior and inferior vena cavae (and coronary sinus), while the left atrium receives oxygenated blood from the lungs via the pulmonary veins. Blood then moves from the atria into the ventricles through the atrioventricular valves. The ventricles are the pumping chambers that send blood out through the major arteries—the aorta to the body and the pulmonary trunk to the lungs. So, since the question asks which chambers serve as receiving centers for blood, the atria are the correct choice.
