Identifying the Correct Heart Chamber
The question asks which heart chamber pumps deoxygenated blood to the lungs for oxygenation. We need to trace the path of deoxygenated blood through the heart.
Blood Flow Pathway
- Deoxygenated blood from the body enters the right atrium.
- From the right atrium, the blood flows into the right ventricle.
- The right ventricle contracts, pumping the deoxygenated blood through the pulmonary artery to the lungs.
- In the lungs, the blood releases carbon dioxide and picks up oxygen (oxygenation).
- Oxygenated blood then returns to the left atrium of the heart.
Conclusion
Based on the blood flow, the chamber responsible for sending deoxygenated blood to the lungs is the right ventricle.
