Answer:

Blood cells constantly die and your body makes new ones. Red blood cells live about 120 days, and platelets live about 6 days. Some white blood cells live less than a day, but others live much longer. There are four blood types: A, B, AB, or O. Also, blood is either Rh-positive or Rh-negative.
