Which part of the heart receives oxygen-poor blood from the body?

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

Answer: (A)

The heart’s right side handles blood that has little oxygen. Oxygen-poor blood returns from the body into the heart and first enters the right atrium via the superior and inferior vena cavae. From the right atrium, blood moves to the right ventricle and is then pumped to the lungs to pick up oxygen. In contrast, the left atrium receives oxygen-rich blood from the lungs, and the left ventricle pumps that oxygenated blood to the body. So, the chamber that receives oxygen-poor blood from the body is the right atrium.
