Miracle of our Nature | Stem Cells Factory
The Bone marrow available inside our bones produces white blood cells, red blood cells and also the platelets. We all know this in our 6th standard. But there is an interesting thing behind this.
Our Body is a super computer which cannot be designed even by the group of all scientists of our history.
Acids and secretions required for digestion are produced in the digestive system or by the organs near by the digestive system. Similarly reproductive cells like sperms and eggs are produced in the reproductive system. This is the proper system to be maintained.
Likewise, as blood cells spreads all over our body, it can be produced in any of our body parts. But those cells are produced only from Bone Marrow.
Why? What is the speciality of Bone Marrow in producing Blood Cells?
Stem cells are the origin cells of our body which later modify themselves to produces different type of cells and tissues. Blood cells are also produced from those stem cells. But these stem cells, and its production factory exists only inside bone marrow for several safety reasons.
For some aquatic animals like Fish, these stem cells exists inside their kidney. So blood is also produced from kidney in them. In Tadpoles, these stem cells were in liver and also in kidney and the blood cells are produced from there.
Are you asking me about the interesting fact in this?
Stem cells are the origin cells of livings. So they has to be kept very safe. When sun light falls on stem cells, it leads to faster DNA changes and genetic changes. This could leads to unwanted and fastest evolution in life.
So to make them safe, those stem cells are kept inside bone marrow where dangerous UV rays of Sun light cannot penetrate. As the fishes are in water bodies, there is a less possibility of sun light to penetrate water. Even though, there is a thin layer protecting kidneys from UV rays.
In case of Tadpoles, stem cells are protected inside kidneys. When they grow as an adult frog, the Stem cell factory is moved to bone marrow like human beings. Because adult frog lives also in land where the possibility of UV rays attack is much higher comparing to Tadpoles.
Similarly, in the first trimestor of human embryo, when the bones are not grown much, the stem cell and blood cells are produced from liver only.
What an intelligent arrangement done by the God? If you don't like the word God, you may use the word nature. How better God or Nature is working forsake of livings? How much it care of us? Wonderful!.

Super. Works well for kidney cleaning.
