Why are the functions of red and yellow bone marrow different?
While red bone marrow is rich with hematopoietic cells that function to produce red blood cells, white blood cells, and platelets, the yellow bone marrow instead stores the adipocytes that function as fat storage.
Which bones produce blood cells?
Blood cells are made in the bone marrow. The bone marrow is the soft, spongy material in the center of the bones. It produces about 95% of the body's blood cells. Most of the adult body's bone marrow is in the pelvic bones, breast bone, and the bones of the spine.
Which bones produce red blood cells?
Most blood cells are made in your bone marrow. This process is called haemopoiesis. In children, haemopoiesis takes place in the long bones, like the thighbone (femur). In adults, it's mostly in the spine (vertebrae) and hips, ribs, skull and breastbone (sternum).
Do bones produce calcium?
Bones are the main storage site of calcium in the body. Your body cannot make calcium. The body only gets the calcium it needs through the food you eat, or from supplements. If you do not get enough calcium in your diet, or if your body does not absorb enough calcium, your bones can get weak or will not grow properly.

Is red bone marrow found in the medullary cavity?
Red bone marrow is primarily found in the medullary cavity of flat bones such as the sternum and pelvic girdle. This type of bone marrow contains hematopoietic stem cells, which are the stem cells that form blood cells.
Where is the bone marrow found?
Bone marrow is found in the bones throughout your body. There are two types of bone marrow. Red bone marrow is involved in production of blood cells, while yellow marrow is important for fat storage. As you age, yellow bone marrow replaces red bone marrow.
Why is bone marrow important?
Bone marrow is crucial for producing blood cells . Therefore, a range of blood-related conditions involve issues with bone marrow. Many of these conditions affect the numbers of blood cells produced in bone marrow. This causes them to share many common symptoms, including:
What is the condition where bone marrow doesn't produce enough blood cells?
Aplastic anemia. Aplastic anemia occurs when bone marrow doesn’t produce enough new blood cells. It occurs from damage to the stem cells of bone marrow. This makes it harder from them to grow and develop into new blood cells.
How do white blood cells work?
There are several types of white blood cells. They all work to help your body fight off infections. Newly produced blood cells enter your bloodstream through vessels called sinusoids. As you age, your red bone marrow is gradually replaced with yellow bone marrow.
What is the function of yellow bone marrow?
Yellow bone marrow is involved in the storage of fats. The fats in yellow bone marrow are stored in cells called adipocytes. This fat can be used as an energy source as needed. Yellow bone marrow also contains mesenchymal stem cells. These are cells that can develop into bone, fat, cartilage, or muscle cells.
Where are stem cells found?
Hematopoietic stem cells that are found in red bone marrow can develop into a variety of different blood cells, including: Red blood cells. These are the cells that work to carry oxygen-rich blood to the cells of the body. Old red blood cells can also be broken down in red bone marrow, but this task is mostly performed in the liver and spleen.
What is the role of bones in the body?
The bones of the skeletal system serve many important functions for the body, from giving your body support to allowing you to move. They also play an important role in blood cell production and fat storage. Bone marrow is the spongy or viscous tissue that fills the inside of your bones. There are actually two types of bone marrow: ...
Overview
Bone marrow is the soft, fatty tissue inside of bone cavities. Components of your blood including red and white blood cells and platelets form inside of your bone marrow.
Function
Bone marrow makes nearly all the components of your blood. It's responsible for creating billions of red blood cells daily, along with white blood cells and platelets. Bone marrow also stores fat that turns into energy as needed.
Anatomy
There are three parts to the anatomy of your bones: compact bone, spongy bone and bone marrow. Compact bone is the strong, outer layer of your bones. Spongy bone makes up the ends of your bones. Bone marrow is in the center of most bones and in the end of spongy bones in your body.
Conditions and Disorders
Directly targeting bone marrow is leukemia, which is a blood and bone marrow cancer. Leukemia forms when a cell mutation occurs in your bone marrow and mutated cells multiply out of control, reducing the production of healthy, normal cells.
Care
Bone marrow is the foundation of your bones, blood and muscles. Keeping your bone marrow healthy focuses on supporting components of your body that grow from bone marrow cells. You can keep your bone marrow healthy by:

When a condition or disease affects bone marrow so that it can no longer function effectively, a marrow or cord blood transplant could be the best treatment option. For some people, it may be the only option.
Why is bone marrow important?
Healthy bone marrow is important for a range of systems and activities.
Why does bone marrow need to be replaced?
Bone marrow needs to replace these cells constantly, as each blood cell has a set life expectancy. Certain conditions may trigger additional production of blood cells. This may happen when the oxygen content of body tissues is low, if there is loss of blood or anemia, or if the number of red blood cells decreases.
Why is bone marrow yellow?
Yellow bone marrow. Yellow bone marrow mainly acts as a store for fats. It helps provide sustenance and maintain the correct environment for the bone to function. However, under particular conditions — such as with severe blood loss or during a fever — yellow bone marrow may revert to red bone marrow.
What causes bone marrow failure?
The most common cause of acquired bone marrow failure in children and adults is acquired aplastic anemia. When the bone marrow’s hematopoietic stem cells are damaged, the body cannot make enough red, white, or platelet blood cells.

The most common cause of acquired bone marrow failure in children and adults is acquired aplastic anemia.
What is the purpose of a bone marrow conditioning treatment?
The goal of the conditioning therapy is to remove the diseased bone marrow cells to make space for the new healthy ones to grow. The conditioning therapy also suppresses the immune system so that the body doesn’t reject the donor’s foreign stem cells. The transplant stem cells are infused into the blood through an IV.
What is aplastic anemia?
Acquired aplastic anemia differs from another disorder similar to bone marrow failure, called myelodysplastic syndromes (MDS), because even though the marrow fails to make enough blood cells, the few that are produced appear normal. With MDS, the bone marrow manufactures abnormal (dysplastic) cells that often have acquired chromosomal abnormalities.
How long does it take for stem cells to grow?
The transplant stem cells are infused into the blood through an IV. It takes about two to four weeks for the new blood cells to grow – during this period, the immune system is still weak and the patient is highly susceptible to viral, bacterial, and fungal infections. Bone marrow failure disorders are often complicated to transplant, so patients, ...
Where do stem cells come from?
Stem cells for transplant can come from the bone marrow or blood. Before receiving the transplant, patients undergo conditioning therapy, which includes chemotherapy and/or radiation, to prepare the body for the transplant. The goal of the conditioning therapy is to remove the diseased bone marrow cells to make space for ...
Can bone marrow failure be inherited?
Many conditions may cause bone marrow failure, but in about 30 percent of cases, no specific cause is identified. Bone marrow failure can be inherited or acquired after birth.
