The average adult has 10-12 pints of blood traveling all over his or her body through the heart, lungs, arteries, veins and capillaries. Blood is an essential part of our bodies that performs these functions:
  • Replenishes oxygen and removes carbon dioxide
  • Distributes essential nutrients to cells
  • Carries away metabolic waste materials for disposal
  • Recognizes antigens (foreign substances) and produces antibodies (immune defense mechanisms)
  • Clots cuts, wounds and scratches to prevent bleeding
