Which side of the heart receives deoxygenated blood?

• A. Left side
• B. Right side
• C. Both sides
• D. None

Answer: (B)

The heart handles deoxygenated blood on the right side. Blood returning from the body is deoxygenated and enters the right atrium via the superior and inferior vena cavae, moves to the right ventricle, and is then pumped to the lungs for oxygenation through the pulmonary artery. The left side handles oxygenated blood, receiving it from the lungs through the pulmonary veins and sending it to the body via the aorta. So, the side that receives deoxygenated blood is the right side.
