The superior and inferior vena cava are the two largest veins in the body. The superior vena cava carries blood from the upper part of the body to the heart. Meanwhile, the inferior vena cava carries blood from the lower part to the heart. The type of blood that veins carry is deoxygenated blood.
Artery
Arteries carry high-oxygen blood or oxygenated blood from the heart towards the rest of the body. The largest artery is the aorta. It is the first artery to which the blood travels after getting oxygenated blood from the lungs.
Capillary
These are tiny blood vessels with thin walls. They transport oxygen and nutrients from the blood through the walls and get into the organs and tissue. They also help in taking waste products away from your tissues.
