Blood Cell Production
Bone Marrow
• Soft, fatty, vascular tissue that fills most bone
cavities
• It is the place where new blood cells are
produced.
• There are two types of bone marrow: red
marrow and yellow marrow.
Red Bone Marrow
• Red color
• Consists mainly of
hematopoietic tissue
-Blood making
• Found in flat bones (pelvis,
sternum, cranium, ribs,
scapula), vertebrae and
spongy epiphyses of long
bones.
• Produces red blood cells,
white blood cells and
platelets

Yellow Bone Marrow
Yellow color
Yellow marrow is found in
the medullary
cavity(diaphysis of long
bones)
Mainly fat cells
During aging red marrow
is replaced by yellow
In cases of severe blood
loss the body can convert
the yellow marrow back
to red

low blood cell count
• Hodgkin’s Disease –found
in lymphnodes, spleen, liver
& bone marrow
