Inferior vena cava
The superior vena cava brings deoxygenated blood into the heart, into the right atrium. The superior vena cava is formed by union of the right and left brachiocephalic (innominate) veins.
The function of superior and inferior vena cava is to take blood to the heart. The two veins will carry blood that is low in oxygen from the body to the heart.
Inferior vena cava and superior vena cava.
The superior vena cava.
The superior vena cava is responsible for delivering deoxygenated blood from the upper portion of your body to the heart.
The Largest Vein in the Heart is the Coronary Sinus, which runs in the atrioventricular groove around the posterior and lateral aspect of the Right Atrium. The Second largest vein in the heart is the Great Vein which lies anteriorly and runs with the Left Anterior Descending or Anterior Interventricular Artery, commonly referred to as the LAD or widow maker.
Your superior vena cava brings blood into the heart from the top section of your body, whereas the inferior vena cava brings the blood in from the bottom half of the body.
