Systemic circulation returns to which heart chamber?

Systemic circulation returns to which heart chamber?

• A. Right atrium
• B. Left atrium
• C. Right ventricle
• D. Left ventricle

Answer: (A)

Systemic circulation carries blood from the body back to the heart and returns it to the right atrium. Veins from the body, including the superior and inferior vena cavae and the coronary sinus, empty into the right atrium. From there, blood moves to the right ventricle and is pumped to the lungs for oxygenation, while the left atrium receives oxygenated blood from the lungs via the pulmonary veins and the left ventricle supplies the body. So the chamber that receives systemic venous return is the right atrium.
