Blood cells

Healthy bone marrow contains stem cells that develop into the three types of blood cells that the body needs:

  • Red blood cells, which carry oxygen to all parts of your body. Red blood cells also remove carbon dioxide (a waste product) from your body's cells and carry it to the lungs to be exhaled.
  • White blood cells, which help fight infections.
  • Platelets (PLATE-lets), which help your blood clot.

It's normal for blood cells to die. The lifespan of red blood cells is about 120 days. White blood cells live less than 1 day. Platelets live about 6 days. As a result, your bone marrow must constantly make new blood cells.
