which large vein carries blood from the head?
superior vena cava
the inferior vena cava is the lower ("inferior") of the two venae cavae, the two large veins that carry deoxygenated blood from the body to the right auricle of the heart: the inferior vena cava carries blood from the lower half of the body whilst the superior vena cava carries blood from the upper half of the body. together, the venae cavae (in addition to the coronary sinus, which carries blood from the muscle of the heart itself) form the venous counterparts of the aorta.

the liver is connected to two large blood vessels: the hepatic artery and the portal vein and common hepatic duct. the hepatic artery carries oxygen-rich blood from the aorta via the celiac plexus, whereas the portal vein carries blood rich in digested nutrients from the entire gastrointestinal tract and also from the spleen and pancreas. these blood vessels subdivide into small capillaries known as liver sinusoids, which then lead to lobules.
