Which chamber receives blood from the systemic veins?

• A. Left Ventricle
• B. Right Ventricle
• C. Left Atrium
• D. Right Atrium

Answer: (D)

Blood returning from the body via the systemic veins arrives first at the right atrium. This chamber acts as the receiving room for venous blood from the body (via the superior and inferior vena cavae, and the coronary sinus). From the right atrium, blood moves to the right ventricle and then to the lungs for oxygenation. In contrast, the left atrium receives oxygenated blood from the lungs, and the left ventricle pumps blood to the body. So the chamber that directly receives systemic venous blood is the right atrium.
