Detailed explanation-1: -Right atrium. This gets oxygen-poor blood from the body through the superior vena cava and the inferior vena cava and pumps the blood to the right ventricle.
Detailed explanation-2: -Oxygen-poor blood returns from the body to the heart through the superior vena cava (SVC) and inferior vena cava (IVC), the two main veins that bring blood back to the heart. The oxygen-poor blood enters the right atrium (RA), or the right upper chamber of the heart.
Detailed explanation-3: -The superior vena cava and inferior vena cava are very large veins that bring deoxygenated blood to your heart to get oxygen. Your inferior vena cava, your body’s largest vein, carries oxygen-depleted blood back to your heart from the lower part of your body (below your diaphragm).
Detailed explanation-4: -The blood enters the heart from the body through the superior vena cava and the inferior vena cava. Then the blood enters the right atrium chamber of the heart. The blood then moves through the tricuspid valve (shown as two white flaps) into the right ventricle chamber of the heart.
