If a physician is concerned about a patient’s bone marrow function, they may order a bone marrow test for cancer or another type of disease. This helps maintain the right environment and provides the sustenance that bones need to function. Yellow bone marrow also aids in the storage of fats in cells called adipocytes. Yellow bone marrow contains mesenchymal stem cells (marrow stromal cells), which produce cartilage, fat and bone. This type of bone marrow can be found in the medullary cavity in the shaft of long bones and is often surrounded by a layer of red bone marrow. The second type of bone marrow found in the body is yellow bone marrow, which gets its name from its high concentration of fat cells, which appear yellow in color.
White blood cells – Help fight infections within the body.Red blood cells – Transport oxygen throughout the body.The three types of blood cells formed from the stem cells within red bone marrow are: Hematopoietic stem cells can turn into three types of blood cells, all of which have important functions that help keep a person alive and healthy. This type of bone marrow contains hematopoietic stem cells, which are the stem cells that form blood cells. Red bone marrow is primarily found in the medullary cavity of flat bones such as the sternum and pelvic girdle. There are two types of human bone marrow: red bone marrow (myeloid tissue) and yellow bone marrow (fatty tissue).
What does bone marrow do?Īs previously discussed, the function of bone marrow is to produce different types of cells that are vital to sustaining life. Bone marrow stem cells can mature into several different kinds of cells, each of which has its own vital functions within the body. Healthy bone marrow is an essential part of the body, as it contains stem cells that produce blood cells and the cells that make up the immune system. Bone marrow is the soft, spongy tissue that is in the medullary cavities (centers) of bones.
