Hemoglobin enables red blood cells to transport oxygen around the body. The RBCC for a healthy adult is approximately 4.2 to 6.2 million cells per cubic millimeter. White blood cells, or leukocytes , are the infantry behind your body's defense against infection. Though the majority of white blood cell activity takes place outside of the circulatory system, these cells use the blood to reach sites of infection. Doctors monitor this amount because any change in your WCC is often a sign of illness or infection.
Platelets are fragments of cells that are less than half the size of red blood cells.
