Heart Trivia

In 1 year, the average human heart circulates from 770,000 to 1.6 million gallons of blood through the body. This is enough fluid to fill 200 tank cars, each with a capacity of 8,000 gallons.

What's a tank car? With a capacity of 8,000 gallons?

Tank car = one of those tanks pulled by 18-wheelers (or on trains). At least, that's my guess...

That makes sense.
