Which one of the following chambers of human heart receives the deoxygenated blood from the body?

Result
Your answer: —  Â·  Correct: B
Explanation

The human heart consists of four chambers designed to separate oxygenated and deoxygenated blood. Deoxygenated blood, which has circulated through the body and collected carbon dioxide, returns to the heart via the systemic circulation [t2][t5]. This blood enters the heart through the superior and inferior vena cava into the right atrium, the upper right chamber [c1][t5]. The right atrium acts as a reservoir for this deoxygenated blood before it passes through the tricuspid valve into the right ventricle [t7][t8]. From the right ventricle, the blood is pumped to the lungs for oxygenation [c1][t3]. In contrast, the left side of the heart deals exclusively with oxygenated blood: the left atrium receives it from the lungs, and the left ventricle pumps it to the rest of the body [c1][t1]. Therefore, the right atrium is the specific chamber that first receives deoxygenated blood from the body.
