Red blood cells are made in the bone marrow.
Blood cells are made in the morrow of bones.
The center of the bones is called the marrow. It is where blood cells are made.
Hematopoiesis is the process of red blood cell production inside of bones.

Bone marrow. Bone marrow is where blood cells are created. Only long bones (with the "hole" in the center) have bone marrow in them. So leg bones and arm bones make blood cells, but rib bones or skull bones do not. So those short, solid, irregular-shaped bones do not create blood cells.
Red blood cells are made in the red marrow of long bones. The marrow is in the central hollow of the shafts of these bones.
Bones create red and white blood cells.
