What do the different blood components do?

  • Plasma: Fluid portion of blood containing water, proteins, glucose, electrolytes, enzymes and hormones and is most important for adequate clotting 
  • Red Cells: Carries oxygen from the lungs to all the tissues in the body and returns carbon dioxide to the lungs 
  • White Cells: Protects against disease and infection 
  • Platelets: Small plate-shaped cells that cluster together to help clot blood when bleeding occurs
