2. Why are red blood cells important?





3. Why are white blood cells important?









Level#2: There are three kinds of solids in blood: platelets, red blood cells, and white blood cells. Platelets are actually pieces of cells. They help blood cells to clump together. This action helps wounds to stop bleeding. Red blood cells deliver oxygen to other body cells. White blood cells fight infection. A protein in red blood cells delivers oxygen to other body cells.
