If a child’s entire circulatory system—we’re talking veins, arteries, and capillaries—were laid out flat, it would stretch for more than 60,000 miles, according to the Franklin Institute. By the time we reach adulthood, our bodies have become home to approximately 100,000 miles of blood vessels. That’s just one of the mind-blowing facts that sound made up (but aren’t).
The fact that our circulatory system stretches over 60,000 miles is mind-blowing! 
It’s amazing to think about how our blood travels such a vast network every day. Nature really knows how to impress! Have you come across any other cool facts about the human body?
