- Slide 14
- The Bone Marrow is soft material in the center of most bones where blood cells are formed (white and red blood cells, platelets).

- In Leukemia, the Bone Marrow produces large numbers of abnormal blood cells.
- Slide 18
- These abnormal cells look different, and don't function properly.
