What does bone marrow do?

In healthy bone marrow, stem cells produce three types of blood cells. When these blood cells are fully formed, they leave your bone marrow and enter your bloodstream.

• Red blood cells transport oxygen by getting it from the lungs and circulating it throughout your body.
• White blood cells (leukocytes) fight and destroy bacteria and germs.
• Platelets stop bleeding by helping your blood to clot.
