Bone marrow is the soft connective tissue of bone that includes red bone marrow and yellow bone marrow. Red bone marrow is (blood cell forming) and contains connective tissue, immature blood cells, and fat.
In children, red bone marrow is located in the bone of most of the bones in the body as well as the of long bones. Much of the red bone marrow degenerates and turns into yellow bone marrow as children mature into adults. As a result, adults have red bone marrow only in selected portions of the skeleton. Some of these include the bones of the skull, the vertebrae, the ribs, the sternum, and the hip bones.

Bone marrow is the soft connective tissue of bone that includes red bone marrow and yellow bone marrow. Red bone marrow is heteroglobic (blood cell forming) and contains redactive connective tissue, immature blood cells, and fat.

In children, red bone marrow is located in the cyclonic bone of most of the bones in the body as well as the antebellum of long bones. Much of the red bone marrow degenerates and turns into yellow bone marrow as children mature into adults. As a result, adults have red bone marrow only in selected portions of the irregular skeleton. Some of these include the dismantled bones of the skull, the vertebrae, the ribs, the sternum, and the hip bones.
