We all know about the bones in our bodies, right? But did you know that inside these strong bones, there is an amazing factory that is essential for our lives? This soft tissue, like a sponge, is called bone marrow . Simply put, this is the main blood-making factory in our body. So today, let's talk about this bone marrow, especially one type of it , red bone marrow, to understand everything in a simple way.
There are two types of bone marrow.
There are two main types of bone marrow in our body. They both have slightly different functions. Let's see what they are.
| Bone marrow type | Description and function |
|---|---|
| Red Bone Marrow | These are the main part of our blood-making factory. They are mostly found inside flat bones like the hip bones, skull, and sternum. The special stem cells inside these are what make the blood cells called red blood cells, white blood cells, and platelets. |
| Yellow Bone Marrow | These are mostly found in the long bones of the limbs. As the name suggests, they are yellow in color because they are mostly made up of fat. This fat provides the necessary nutrition for the bones. Also, this yellow bone marrow contains stem cells. These cells can become bone cells, cartilage cells, or fat cells when needed. |
The amazing work of red bone marrow
We call the stem cells in the red bone marrow ``Hematopoietic stem cells''. These are not normal blood cells, but a type of stem cell that can make all other blood cells. This process of making new blood cells is called Hematopoiesis in medicine. In this way, three main types of cells are formed.
1. Red Blood Cells
These are the ones that carry oxygen throughout our bodies. The protein inside red blood cells called hemoglobin is what picks up oxygen from the lungs and delivers it to all the tissues in the body. This hemoglobin is what gives our blood its red color. It is also these red blood cells that bring carbon dioxide produced in the tissues back to the lungs.
2. White Blood Cells
These are our body's army . These white blood cells protect us from diseases by fighting germs like viruses and bacteria that enter the body. There are different types of these, and each type fights germs in a different way.
Imagine, if our body is a country, the white blood cells are the various security forces in that country, such as the army, navy, and air force. Everyone works together to protect the country (the body).
| White blood cell type | What to do simply |
|---|---|
| Lymphocytes | These produce antibodies and destroy germ cells. |
| Granulocytes | They go to the sites of infection and fight germs directly. |
| Monocytes | These become 'macrophages' and engulf foreign cells that have entered the body. |
3. Platelets
When you have a small wound and start bleeding, the bleeding stops after a while, right? That's what these platelets help with. As soon as there's a wound, these cells come to the site, join together, form a blood clot, and stop the bleeding .
Bone marrow and our health
Now you probably understand how important bone marrow is to our health. Sometimes, due to various reasons, the functioning of our bone marrow can be damaged. Then the work of this blood cell factory gets disrupted. These are some of the diseases that can occur due to this.
- Cancer: Various types of cancer can develop in the bone marrow. Leukemia is one of the main types of cancer. In this, a type of white blood cell that is not working properly begins to divide and multiply uncontrollably. When these useless cells fill the body, the production of healthy white blood cells, red blood cells, and platelets stops, and the body is unable to fight infections.
- Aplastic Anemia : This is a rare condition. This occurs when the bone marrow is damaged and the stem cells are lost. This causes the production of blood cells to stop completely.
- Anemia: This is a very common condition. It can occur when the body is deficient in iron, vitamin B12 , or folate . These nutrients are essential for the bone marrow to make red blood cells and hemoglobin. For someone with anemia,
- Always feeling tired
- I feel lifeless.
- I have difficulty breathing even after a little exertion.
- The skin turns pale.
- I feel faint.
- Plasma Cell Disorders: Plasma cells are a type of white blood cell that makes antibodies. If these cells grow too much without control, it can weaken the immune system and damage organs. Multiple Myeloma is a type of cancer that develops in this way.
- Other diseases: In conditions like Myelodysplastic Syndromes and Myeloproliferative Neoplasms , the bone marrow either makes too many of the wrong types of cells or too many of one type of cell. This causes a shortage of other cell types and causes various problems.
What are the treatments for these diseases?
If you are diagnosed with a bone marrow disease, your doctor will determine the best treatment for you. Treatment varies depending on the type and severity of the disease. Common treatments include:
- Bone marrow transplant
- Blood transfusions
- Giving iron, vitamin B12, or folate as pills, vitamin injections, or saline
- Anti-cancer drugs (Chemotherapy)
- Immune system suppressing medications
Often, there may be no major symptoms of this type of disease at first. You may find out through your annual blood test, which meansA complete blood count (CBC) is the only way to tell. Therefore, it is very important to always take care of your health and consult a doctor if you feel unwell.
Take-Home Message
- Bone marrow is the main factory inside our bones that produces the blood cells our body needs.
- Red bone marrow produces all three types of cells: red blood cells (which carry oxygen), white blood cells (which fight germs), and platelets (which help blood clot).
- If there is a problem with the functioning of the bone marrow, various diseases such as leukemia and anemia can occur.
- If you have symptoms such as constant fatigue, paleness, and occasional bruising, don't ignore them.
- If you have any doubts about your health, do not delay and consult your doctor.
