Did you know that if all the capillaries of a human lung were rolled out onto a tennis court...
The game would likely be cancelled
There are over 60,000 miles of arteries, veins and capillaries in the human body. If you took all of yours and laid them end-to-end,
You'd die.
"If you removed all the arteries, veins, & capillaries from a person's body, and tied them end-to-end, the person will die." -- Neil deGrasse Tyson
