We are always keen to know about the nature around us. This nature seems to us to be a mysterious thing which contains many unresolved mysteries inside it and for this reason most people have a lot of knowledge about the things around them but they don't know the interesting and necessary facts related to their human body. In fact, there are some such secrets hidden inside our human body, due to which they can prove to be very beneficial for human society.

So let's know about some such essential and interesting facts about our human body.

Fact No. 1

You must have heard about a biomolecule present inside our human cells which is the main ingredient of survival and population growth of all living species present on our earth, its name is DNA. We find that this dna present inside our cells is very small in size, because we know that our cells are also microscopic. A human body has approximately 37 trillion cells and a cell has about 2 meter long dna. So in this way the total length of the dna of our body is about 6.2 × 10¹² meters.

And you will be very surprised to know that this is enough to cover 17 times, the distance between sun and pluto.

Fact No. 2

Although every human is quite different from each other, but do you know that in this world, dna of every human being is 99.9% similar to each other, but what is the thing that helps us to identify everyone. That is the remaining 0.1% portion of our dna which is different in every human being, due to this we look different from each other. How interesting is this dna world!

Fact No. 3

As you know, twins are almost identical in appearance. But it is not necessary that all the twins look alike. Those twins who look alike, almost every part of their body looks the same, such children are called identical twins. At the genetic level, their dna exactly matches each other. Conversely, some twins do not look alike, they are called fraternal twins, and at the genetic level certainly they don't have identical dna.

Fact No. 4

In the average human body, the amount of bacterial cells is 10 times higher than that of human cells. Many of you may be wondering how this can happen, because we wash our hands many times a day and take full care of our cleanliness, but how can there be so many bacteria in our body. Actually, some bacteria remain present in our body because they are not harmful to our body, as they help us in completing many processes of our body.

Fact No. 5

In his entire life, the average person walks almost as much as the distance from which he can complete five rounds of the world. If we calculate that how much we can walk till the age of 80 years, then we will know that by the time of 80 years, the average person has walked 1,10,000 miles, which is equal to five rounds of the world.

Fact No. 6

We eat so much delicious food throughout the day, but do you know how we get the taste of food. The taste of food is revealed to our body by saliva. As soon as you put anything in your mouth, immediately the secretion of saliva occurs in our mouth so that our brain detects the taste of that food and then we get to know the original taste of food.

Fact No. 7

As you may know that a human has only one heart and not only humans but some animals also have only one heart but do you know that octopus has 3 hearts, 9 brain and blue blood. This is the most interesting fact but are you not amazed that what is the work of these so many stuffs in the body of octopus?

Our own body is full of many mysteries, so many scientists are still doing research on our body and this is a very good thing for us because it can provide treatment for many diseases that are not yet treated and also many secrets of our body get revealed in front of us.
