Paucity of vasculature. In adults, red bone marrow is primarily found in the flat bones, such as the pelvic girdle and the sternum. In children, it is found in the medullary cavity of the long bones, such as the femur.
Bone marrow is the soft, flexible connective tissue within bone cavities. A component of the lymphatic system, bone marrow functions primarily to produce blood cells and to store fat.Bone marrow is highly vascular, meaning that it is richly supplied with a large number of blood vessels. There are two categories of bone marrow tissue: red marrow and yellow marrow. Red marrow contains hematopoietic stem cells that produce two other types of stem cells: myeloid stem cells and lymphoid stem cells. 2  These cells develop into red blood cells, white blood cells, or platelets.
