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.
The amount taken is only about 400cc. This amount is equal to about a pint of blood. Im not sure what the density of blood is but it couldnt be too far off from water so im guessing that a pint of blood is only around 16oz. If you are donating for the purpose of losing weight I guess technically for about 10 min.
