Which heart chamber sends deoxygenated blood to the lungs for oxygenation?

Which heart chamber sends deoxygenated blood to the lungs for oxygenation?

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

Answer: (A)

The right ventricle is the chamber that sends deoxygenated blood to the lungs. Blood from the body returns to the heart and enters the right atrium, passes through the tricuspid valve into the right ventricle, which then contracts to push that blood through the pulmonary valve into the pulmonary arteries and toward the lungs for oxygenation. The left-side chambers handle oxygenated blood, with the left atrium receiving it from the lungs and the left ventricle pumping it to the rest of the body.
