IVC delivers blood into which chamber of the heart?

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

Answer: (B)

The inferior vena cava (IVC) is responsible for carrying deoxygenated blood from the lower half of the body back to the heart. It terminates by delivering this blood directly into the right atrium. The right atrium then receives blood from both the IVC and the superior vena cava, which collects blood from the upper body. Once the right atrium is filled, blood moves through the tricuspid valve into the right ventricle, where it is then pumped to the lungs for oxygenation. This process is crucial for maintaining proper circulation and oxygen delivery throughout the body.

In summary, the IVC specifically supplies blood to the right atrium, making this the correct answer. The other options do not reflect this anatomy and flow of blood within the heart.
