There's more than a milk jug full of fluid coursing through your veins, where it functions somewhat like a courier service. Blood is responsible for both delivering the things your body desperately needs—like oxygen—and carting off the things it desperately needs to throw out, like the toxic wastes that end up being filtered out of the body by the kidneys. And it does all of this very, very fast. The heart, the organ responsible for getting all that blood to move around, pumps as much blood as is in the body every minute; when you're sitting still, that is. Up your activity level and your heart can end up pumping more than five gallons of blood per minute.
