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.
blood cannot be replaced as you only have 8 pints throughout your whole life.. is obviously a false statement. If you only have 8 pints for your entire life span, how can people donate 1 pint multiple times in your life? You don't just donate until you dry up. If someone could answer how long it takes for the blood to replace, that would be great as I do not know the answer to that question myself. I do, however, know that blood does regenerate. The fluid component of the blood (plasma) is replaced in approximately 24 hours provided you remember to drink enough water.
