the inferior vena cava
, which carries deoxygenated blood from the lower half of the body back up to the heart.
Where are large veins located?
The largest veins in the human body are the
venae cavae
. These are two large veins which enter the right atrium of the heart from above and below.
What are the 2 largest veins in the human body?

Where is the largest artery in your body?

exits the left ventricle of the heart
.
Is the longest vein in the body?

is the longest vein in the body; it runs from inside of the ankle, to the inside of the knee, and up to the groin where it joins the femoral vein (saphenofemoral junction).
What is the most important vein in your body?
The
superior vena cava
is the large vein that brings blood from the head and arms to the heart, and the inferior vena cava brings blood from the abdomen and legs into the heart.
Are veins thick or thin?
Veins are
generally larger in diameter
, carry more blood volume and have thinner walls in proportion to their lumen. Arteries are smaller, have thicker walls in proportion to their lumen and carry blood under higher pressure than veins.
What is the smallest vein in the human body?
The smallest veins in the body are known as
venules
. Blood reaches the venules, from the arteries via the arterioles and capillaries. The venules join into larger veins which eventually carry the blood to the largest veins in the body called vena cava.

How can you tell the difference between an artery and a vein?

carry blood low in oxygen
from the body back to the heart for reoxygenation.
Can you see your arteries?

The great saphenous vein
is the major superficial vein of the medial leg and thigh. It is the longest vein in the human body, extending from the top of the foot to the upper thigh and groin.

venules
.
What is the most important vein?
Major veins. A vein is defined as a vessel that conducts blood from the periphery to the heart. All veins carry deoxygenated blood–except for the pulmonary vein. The largest veins are
the superior and inferior vena cava
, and both drain directly into the right atrium of the heart.
