Blood donation is very important topic and it is interesting to know that a blood donation saves approximately 4.5 million people in America every year. The term blood donation is associated with drawn blood from a donor and this blood will eventually be given to other person who needs it. The blood taken from the donor must not be infected with any virus and the donor needs to be healthy. If medical conditions were present, the blood will become contagious and the condition will be transferred to the recipient of the blood. The blood donation can be done for money, but it is mostly done as a charity act. The common amount of blood drawn in one time is 450ml, but this blood has short lifespan and this is a problem.
