Blood is a mixture of cells and plasma. The heart pumps blood through the arteries, capillaries and veins to provide oxygen and nutrients to every cell of the body. The blood also carries away waste products. The average adult has about five liters of blood; it makes up 7 to 8 percent of a person's body weight. Approximately 2.75 to 3 liters of blood is plasma and the rest is the cellular portion. Every person has one of the following blood types: A, B, AB, or O. Also, every person's blood is either Rh-positive or Rh-negative. So, if you have type A blood, it's either A positive or A negative. A blood transfusion is a safe, common procedure in which blood is received through an intravenous (IV) line inserted into one of the blood vessels of the person.Blood transfusions are used to replace blood lost during surgery or a serious injury. A transfusion also might be done if a person’s body can't make blood properly, because of an illness. Blood transfusions are very common and blood donation does not affect the health of a person who donates the blood.
