How to approach this question
Deoxygenated blood is handled by the right side of the heart. The pumping chambers are the ventricles (the lower, more muscular chambers). Identify the right ventricle on the diagram.
Full Answer
C.C✓ Correct
C
Deoxygenated blood returns from the body to the right atrium (D). It then passes to the right ventricle (C). The right ventricle is a muscular chamber that contracts to pump the deoxygenated blood through the pulmonary artery to the lungs, where it will pick up oxygen. Therefore, C is the part that pumps deoxygenated blood to the lungs.
Common mistakes
✗ Choosing the right atrium (D) - it receives deoxygenated blood but doesn't pump it to the lungs.
✗ Choosing the left ventricle (B) - it is a pumping chamber, but it pumps oxygenated blood.
