Today we are going to talk about a very important part of our body that we don't think about much. Have you ever wondered what's inside your bones? That's where this hero called Bone Marrow lives. He silently serves us a great service.
What is Bone Marrow? Simply put...
Bone marrow is the soft, oily tissue that fills the cavities of our bones, or rather, the inside of our bones. Think of it like the marrow inside a chicken drumstick. But it's much more complex and important than that. The red blood cells, white blood cells, and platelets in our blood are all made in this bone marrow. Isn't it amazing?
What service does bone marrow provide to our body?
Bone marrow isn't just something inside your bones. It's the factory that produces most of the essential cells in our blood. Imagine, it makes billions of red blood cells a day!
- Red blood cells: These are what carry oxygen throughout our bodies. Without them, we couldn't breathe.
- White blood cells: They are like our body's defense system. They fight germs and protect us from disease.
- Platelets: These platelets help stop bleeding and form blood clots when we get injured.
Not only this, bone marrow does something else. That is to store fat . When we need it, we convert this fat into energy. So, can we live without bone marrow? Absolutely not! It is a vital part of our body.
Where is the bone marrow located? How can it be seen?
Bone marrow is found in the middle of most of the large bones in our body and at the ends of the spongy bones . It fills the cavities inside the bones. Inside these cavities are the marrow and blood vessels.
In terms of appearance, bone marrow is a soft tissue that looks like a sponge, like jelly, or like jam . It comes in two colors: red and yellow . Red bone marrow is red because it makes red blood cells.
Is it true that there are two types of bone marrow? (Types of Bone Marrow)
Yes, that's right. There are two types of bone marrow in our bodies. This classification is based on their color. On average, an adult has about 2.5 kilograms of red and yellow bone marrow.
- Red Bone Marrow:
- Its main function is to make blood cells . In medicine, we call this process ``Hematopoiesis''.
- Hematopoietic stem cells, a special type of stem cell found in the red bone marrow, are what make red blood cells, white blood cells, and platelets.
- Yellow Bone Marrow:
- Its main job is to store fat .
- Yellow bone marrow also contains two special types of stem cells: fat cells (Adipocytes) and mesenchymal stem cells .
- These cells store fat for energy production and also help our bodies grow the bones, cartilage , muscles, and fat cells they need.
The amazing thing is that when we are young, up until about 7 years old, our bodies are almost entirely made up of red bone marrow . As we grow older, yellow bone marrow gradually starts to replace the red bone marrow.
What is bone marrow made of?
Bone marrow is mainly made up of stem cells . These stem cells create red bone marrow. Then, the red bone marrow produces the blood cells and platelets that our blood needs. If we take yellow bone marrow, it contains mostly fat and the stem cells that make our bones and cartilage.
What are the diseases that affect the bone marrow?
Since the bone marrow is the primary site where our blood is made, if there is a problem with the bone marrow, it directly affects our blood.
- Leukemia: This is a cancer that directly affects the bone marrow and blood. It happens like this: A mutation occurs in a cell in the bone marrow, causing the mutated cells to divide and multiply uncontrollably. This causes the production of healthy cells to decrease.
- Multiple Myeloma: This is a condition in which cancerous plasma cells form in the bone marrow.
- Aplastic Anemia: In this condition, the bone marrow does not produce enough blood cells.
- Polycythemia Vera: This is when the body produces too many red blood cells, causing the blood to thicken.
- Myelodysplastic Syndromes: This is a group of diseases in which the bone marrow does not produce enough healthy blood cells, resulting in anemia .
What are the symptoms of this type of disease?
There are several common symptoms that can occur with a bone marrow disease. If you notice these, it is important to seek medical advice.
- Easy bleeding and bruising.
- Constant fatigue.
- Frequent infections.
- Feeling of muscle weakness.
What tests are done to check the health of the bone marrow?
Doctors usually do two tests to check if there are any problems with your bone marrow or blood cells.
- Bone Marrow Aspiration: This involves using a special needle to remove a small amount of fluid and cells from the bone marrow. The sample is also called a bone marrow concentrate . This test can tell you a lot about the types of cells in the bone marrow, whether they are normal or abnormal, and the nature of the cells.
- Bone Marrow Biopsy: This involves taking a small sample of bone marrow using a large needle. This biopsy can show exactly where the cells are in the bone marrow, how many there are, and what types of cells they are.
"Does this test hurt?" You may ask. You will be given anesthesia before the test, so you will not feel any pain during the test. However, after the test, you may feel some bruising and soreness for a few days where the needle was inserted. This can vary from person to person.
Can I donate bone marrow? What happens if I donate?
Yes, it is definitely possible! Healthy bone marrow and the cells it produces are essential for humans to survive. Sometimes, healthy bone marrow cells are damaged due to cell mutations. In that case, a bone marrow transplant is a good treatment option, especially for people with blood cancers like leukemia .
In a bone marrow transplant, healthy cells from a healthy donor are infused into the patient's bloodstream. The donor's cells then help the patient's body produce healthy red blood cells, white blood cells, and platelets.
Is there a treatment for bone marrow diseases?
Treatments for bone marrow diseases vary depending on the nature and severity of the disease. Don't worry, there is often a cure.
- Antibiotics
- Blood Transfusions
- Bone Marrow Transplant
- Chemotherapy
- Supportive care to relieve symptoms
- Stem Cell Transplant
How do we keep our bone marrow healthy?
Bone marrow is like the foundation of our bones, blood, and muscles. So to keep our bone marrow healthy, we need to take good care of the parts of our body that develop from bone marrow cells.
- Eat a diet rich in protein: things like lean meat, fish, beans, nuts, milk, and eggs.
- Get vitamins: especially iron, vitamin B9 (folate), and vitamin B12.
- If you have an underlying medical condition that could cause bone marrow abnormalities as a side effect, get it properly treated.
Finally, things to remember (Take-Home Message)
Now you know that bone marrow is a little hero inside our bones, doing a very quiet job. It's the one that makes the cells we need for our blood and stores fat for energy.
The most important thing is that to keep our bone marrow healthy, we need to eat a balanced diet, get the necessary vitamins, and take care of our overall health. Because if the bone marrow is healthy, our blood is healthy, and many things in our body are healthy! If you have any doubts or problems, don't forget to talk to a doctor.
