Bone Marrow: Its Functions And Importance

In the human body, the bones of the skeletal system serve many important and vital functions for the body, from giving your body support to allowing you to move. Bone marrow is a spongy substance that is found in the middle of your bones and they are usually present in the tough, hard bones such as the hip and thigh bones. There are two types of bone marrow, red and yellow are very crucial and essential for one’s survival. Any disease or infection affecting the functional effectiveness of the bone marrow may be fatal and risky. The risks of bone marrow transplant depend on many factors like the type of bone marrow transplant, disease, age and health of the patient, etc.


Bone marrow is important for the body because it produces bone marrow stem cells and blood products. Hematopoiesis is the process by which the bone marrow produces red blood cells, white blood cells, and platelets. It is divided into two varieties, each of which serves a distinct purpose.

The main function of bone marrow is to produce different types of cells that are vital for sustaining. A lot of factors and circumstances can affect the health of the bone marrow and cause damage or impair its ability to produce a normal amount of healthy cells. The red blood cells, platelets, and most of the white blood cells are formed in the red bone marrow, on the other hand, the yellow bone marrow produces fat, cartilage, and bone.

  • It replaces non-functional  bone marrow that has been damaged due to certain health conditions a person might be facing
  • Restore the bone marrow’s function after it has been damaged due to treatments such as high-dose chemotherapy or radiation therapy
  • It prevents  further damage caused by certain genetic diseases in certain cases
  • The bone marrow also regenerate the immune system in order to fight existing or residual cancers such as leukemia


Bone marrow is important to the body as it constitutes cells that make up the immune system as well as the stem cells that produce blood cells in the body. Stem cells in the bone marrow mature in the body into a variety of types of cells, each of which has specific functions that benefit the body.

As one ages, the red bone marrow is gradually replaced with yellow bone marrow. By adulthood, the red bone marrow can be found only in few bones including:

  • Skull
  • Vertebrae
  • Sternum
  • Ribs
  • The ends of the upper arm bone
  • Pelvis
  • The ends of the thigh bone
  • The ends of the shin bone

Here are some of the issues that can occur within bone marrow, as well as as a result of problems with bone marrow:

Leukemia– Leukemia is a blood malignancy in which the bone marrow generates aberrant white blood cells.

Aplastic anemia– Aplastic anemia is a condition in which the bone marrow stops producing red blood cells.

Myeloproliferative disorders– Chronic myelogenous leukemia (CML), polycythemia vera, primary myelofibrosis, essential thrombocytopenia, chronic neutrophilic leukemia, and chronic eosinophilic leukemia are examples of myeloproliferative diseases. All of these illnesses have an effect on the generation of white blood cells, red blood cells, and platelets.

Lymphoma– Lymphoma is a type of cancer that begins in the lymphocytes and affects the immune system.

The bone marrow is an important part of the body that produces many different types of blood cells. The loss of bone marrow can have a negative impact on an individual’s quality of life and lifespan.

bone marrow transplant may be required when the doses of chemotherapy or radiation required to cure a malignancy are so high that the treatment permanently damages or destroys a person’s bone marrow stem cells. If the bone marrow has been destroyed by a disease, bone marrow transplants may be required.
