How Long Are Human Veins?

When the human circulatory system and veins are stretched out in a straight line, it has a total length of approximately 60,000 miles. The human veins circulate approximately 6 quarts of blood throughout the body on a daily basis.

As it circulates around the body, human blood travels a total distance of 12,000 miles. The movement of the blood through the circulatory system is facilitated by a pumping system fueled by the heart. The average human heart pumps approximately 1 million barrels of blood over a lifetime. An eighth of all the blood supplied to the human body is used by the skin.
