How many times can your blood vessels wrap around the equator?

Answer 1

At least twice, perhaps even two-and-a-half times! Not that anyone's tried to physically attempt this before, but some boffins have made calculations based on the fact that none of our several trillion respiring cells are more than a few micrometres from a capillary.

Answer 2

I’m a physician and the numbers I have read are 60,000 to 100,000. That is if all blood vessels (arteries, capillaries, and veins) are place end-to-end that’s how long they would be. Obviously if we’re talking a small child then the number is closer to 60,000 but if we’re talking an adult it’s closer to 100,000. The circumference of the earth is ~ 25,000 miles so the vessels in an adult could wrap around the earth 4 time. This is why it’s so important to eat a plant based diet. That’s a lot of Plumbing to keep clean. No wonder stroke and heart attack are so common with our Western diet that’s high in animal products.

Answer 3

Zero, they are very small.
