Why can cells in the bone marrow produce both red and white cells

1.Bone marrow produces red blood cells, platelets, and white blood cells. Lymphocytes are produced in the marrow, and play an important part in the body's immune system.

Explanation:

2.After entering the bloodstream, the hematopoietic stem cells travel to the bone marrow. There, they begin to produce new white blood cells, red blood cells, and platelets in a process known as engraftment.

3.Red blood cells are an important element of blood. Their job is to transport oxygen to the body's tissues in exchange for carbon dioxide, which they carry to the lungs to be expelled. Red blood cells are formed in the red bone marrow of bones. Stem cells in the red bone marrow are called hemocytoblasts.
