1 One out of every 10 people entering a hospital needs blood. 2  Just one pint of donated blood can help save as many as three people's lives. 3  The average adult has 10 pints of blood in his or her body.
A unit of blood donated is between 450 and 500 mililiters. Since a liter of water weighs 2.2 pounds, a pint or unit of blooâ¦d weighs a bit more than one pound.   So, lose weight, give blood, save a life! Go to www.GiveLife.org to register to donate blood and find a local blood bank or mobile blood drive. It only takes about an hour to donate blood.
