PATHOLOGY

Detailed explanation-1: -This vast system of blood vessels-arteries, veins, and capillaries-is over 60, 000 miles long. That’s long enough to go around the world more than twice!

Detailed explanation-2: -If you were to lay out all of the arteries, capillaries and veins in one adult, end-to-end, they would stretch about 60, 000 miles (100, 000 kilometers). What’s more, the capillaries, which are the smallest of the blood vessels, would make up about 80 percent of this length.

Detailed explanation-3: -There is anywhere between 60, 000-100, 000 miles of blood vessels in the human body. If they were taken out and laid end-to-end, they would be long enough to travel around the world more than three times. Teeth are considered part of the skeletal system, but are not counted as bones.

Detailed explanation-4: -Your body contains about 60, 000 miles of blood vessels. There are three types of blood vessels: Arteries carry blood away from your heart. Veins carry blood back toward your heart.
