Myeloid Tissue or Bone Marrow is a soft, elastic spongy tissue that exists within the bone, and its primary function is to form blood cells and put them into the body. Also known as other names, including: bone marrow, bone pulp, bone marrow.
There are two basic types of bone marrow in the human body:
- Red bone marrow, which is made up of stem cells that produce blood.
- Yellow bone marrow, which consists of a group of tissues and fat or lipid cells. This bone marrow is not blood-producing.
The red bone marrow consists of a networked tissue called the Storma. It also consists of certain types of cells and tissues, such as stem cells that make up all types of blood cells: red blood cells, white blood cells, and platelets. Stoma is the frame and place where stem cells form blood.
The yellow bone marrow consists of many tissues and fat or lipid cells. Yellow bone marrow is found in many bones of the body where the red bone marrow is located, where doctors point out that the red bone marrow exists in humans in all bone cavities at the age of seven, where it exists in all bones in embryos and children. After seven years of human life, the red bone marrow begins to decline gradually leaving the yellow bone marrow composed of the cells and fatty tissues.
This gradual decline of the red bone marrow continues until the age of twenty-one. Only after that age is it confined to the large bones in the body, such as the thigh and leg bones, the pelvis, the shoulder, the skull and the spine. However, the yellow bone marrow may return to a red marrow in cases where the body needs to form blood.
The most important functions of the red bone marrow:
- Production of different blood cells.
- Organize the process of entering the blood cells to the body when needed.
- Eliminate advanced blood cells in the tooth.
- It is a reservoir of the important iron component, which contributes to the formation of hemoglobin.
Red bone marrow may be exposed to many health problems and diseases, including infections and diseases that affect its functions and production of blood, and the person is exposed to anemia. It may also be exposed to cancer, which is known as leukemia. In cancer cells, the bone marrow produces uncomplicated aggressive white blood cells, damaging healthy blood cells.
