Learn About Blood

Did you know...?

  • Approximately 60 percent of the population is eligible to donate blood, but only 5 percent actually does.
  • In one day, your blood travels 12,000 miles – four times the distance across the United States from coast to coast!
  • The human heart creates enough pressure to squirt blood up to 30 feet.
  • Every second, 8 million blood cells die in your body, and 8 million more are made.
  • Your heart beats over 3 billion times in your life. That's about 100,000 times a day!
  • An adult body has about 10–15 pints of blood. A newborn has only about 1 cup of blood.
  • Blood travels away from the heart and back again in approximately 20–60 seconds.
