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 that contains all the parts is called whole blood. You can donate blood at American Red Cross clinics or other clinics or blood banks. You may be able to donate during blood drives at your workplace. About 1 pint (480 mL) of blood is taken when you donate. It takes about 10 minutes.
