Detailed explanation-1: -What does the vena cava do? Your superior vena cava and inferior vena cava have the important function of carrying oxygen-poor blood to your heart’s right atrium, where it moves into your right ventricle and then to your lungs (through your pulmonary artery) to trade in carbon dioxide for oxygen.

Detailed explanation-2: -The superior vena cava carries blood from the head, neck, arms, and chest. The inferior vena cava carries blood from the legs, feet, and organs in the abdomen and pelvis. The vena cava is the largest vein in the body.

Detailed explanation-3: -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.

Detailed explanation-4: -Right atrium: Receives blood returning to the heart from the superior and inferior vena cava; transmits blood to the right ventricle, which pumps blood to the lungs for oxygenation.

Detailed explanation-5: -The blood vessels include the superior and inferior vena cava. These bring blood from the body to the right atrium.
