Too many factors come into play to answer this question. Everyone is different, the larger you are, the more vasculature you have.
12,000 miles
THERE ARE 20 ARTERIES IN THE HUMAN BODY.
60,000 miles, or the equivalent of 2½ times around the world!
25,000 to 60,000 miles!
there are 3 different types: capillaries, veins, and arteries
3, arteries, veins, and capillarity's. well...thats wat kinds are in your body.
There are three types of blood vessels. There are veins, arteries, and capillaries.
Arteries are not close to the surface in most places on the body because they need to be protected. But there are many places, called endangerment sites, where they are close to the surface, so health care workers need to be cautious when working in these areas. Usually, in most place on the body arteries and veins are close together, so are nerves.
Mainly, they're made out of the same tissues in the same order, the difference being how thick those tissues are, a lot thicker in arteries than in veins. They're both responsible for blood flow, being the arteries responsible for blood flow from the heart to the tissues and veins responsible for blood flow from the tissues to the heart.
There are millions of veins present in human body, which are not accounted yet accurately. Every organ has veins running from it branching off into many more capillaries. Approximately the total length of the veins in the human body ranges from 60,000 - 100,000 miles including the capillaries.
There are too many to count. There are also variations from person to person. The biggest arteries branch into smaller arteries and those branch into smaller and smaller arteries down to the arterioles, which are very small and there are many of them. Some people say there are millions of arteries in the human body. One source says there are so many arteries in the body that if you laid them end to end, they would be about 60,000 miles long.
The length of veins in the human body can range from 50,000 to 100,000 miles, depending on which anatomy textbook you're referencing (this also depends, of course, on the age of the body).
