Question

Deoxygenated blood from the body cell enters the heart through the blood vessels named superior and inferior vena cava

Please give the correct answer

Answer 1

Answer:

The right atrium receives deoxygenated blood through the superior and inferior vena cava from the body and pumps it to the right ventricle through the tricuspid valve, which opens to allow the blood flow through and closes to prevent blood backing up the atrium. The left atrium receives oxygenated blood through the pulmonary veins from the lungs.
