WHAT IS BONE MARROW?
Bone marrow is a sponge-like substance often found in the center of bones in the human body. It is one of the important parts of human bones which caters to produce different types of cells in the human body.
The bone marrow is responsible to produce bone marrow stem cells which further help in the production of different blood cells. Red blood cells, White blood cells and platelets are most important among the blood cells produced due to the presence of bone marrow in human body.
The bone marrow produces almost 200 billion new blood cells on daily basis in the human body.
The bone marrow stores fats in the body, it fills up the bones in the human body. Significantly it allows a person moveability.
TYPES OF BONE MARROW
There are basically two types of bone marrow present in the human body.
1.RED BONE MARROW
The red bone marrow helps the body produce blood cells which play a vital role in the production and circulation of blood along the body also they have a significance in fighting with diseases in the human body.
2.YELLOW BONE MARROW
Storing fats in the body is responsibility fulfilled by the yellow bone marrow.
HOW DOES AGE AFFECT THE BONE MARROW?
When it is bone marrow in the discussion age is one of the topmost factors affecting the bone marrow in the body. Moreover, the bone marrow in adults is seen to be comprised of only one type. The yellow bone marrow covers major part of the bones in adults, this does not indicate any specific age, but the red bone marrow is certainly replaced by the yellow bone marrow with time. This tells us that adults have less tendency to produce blood cells. The red bone marrow is at some point completely replaced by the yellow bone marrow.
The time when less red bone marrow is left in the body, this condition is called Aplastic Anemia.
WHAT IS APLASTIC ANEMIA? (Shortness of Red bone marrow)
Aplastic anemia is a condition in which the human body fails to produce all kind of blood cells which is because of the deficiency of stem cells which are present in the bone marrow. The aplastic anemia targets the red bone marrow
This condition is common in old, aged people, The blood producing cells either have less production or they stop producing blood for the human body.
SYMPTOMS OF APLASTIC ANEMIA
A list of symptoms is seen in people having aplastic anemia:
- Upset stomach (nausea)
- Lack of energy or tiring easily (fatigue)
Symptoms of aplastic anemia may vary among people.
SIDE EFFECTS OF APLASTIC ANEMIA
The aplastic anemia is when the blood cells stop producing enough blood for the body, This leads to the effects:
1.RED BLOOD CELLS:
The red blood cells in the body become less, this makes the hemoglobin levels to become low in the body. Hemoglobin is present in the body to carry oxygen to various parts of the body.
2.WHITE BLOOD CELLS:
If white blood cells are low in quantity, The body loses its power to fight against different infections and diseases. This leads to the body getting infections which may not vanish for a long while.
Platelets are vital for the body to have a good thick blood. The density of blood becomes less when platelets count is low in the body, this way blood becomes too thin, and it does not clot the way it should.
YELLOW BONE MARROW
When it comes to yellow bone marrow, It is only found in the long bones of human body.
At birth, there is no yellow bone marrow in the human body but, By age seven half of the red bone marrow is replaced with yellow bone marrow.
FUNCTION OF YELLOW BONE MARROW
The yellow bone marrow as already discussed is responsible to store fats in the body.
Along with the storage of fats the yellow bone marrow also helps with the production of fats, bone and cartilage. The functionality of storing fat is labeled as adipocytes. This helps the bones function properly.
Coupled with these things the yellow bone marrow also plays a vital role when the body is at death risks, The yellow bone marrow replaces itself with red marrow in life threatening circumstances.
To summarize, the bone marrow is a part of the human body present in the center of bones. There exist two kinds of bone marrow, Firstly the Redbone marrow which is responsible for the production of blood cells for the human body. However, With time the red bone marrow is replaced by the yellow bone marrow which is the second type of marrow in the body. It is responsible for the accumulation of fats in the human body. The yellow bone marrow does not only store fat, but it has the ability to replace itself with red bone marrow when the human body is at mortality risk.
