The human body looks simple from the outside, doesn’t it? But, science has taught us how complex our bodies are.
Right from the very start of human evolution, our ancestors have been through beautiful changes. The minor changes through years and years have bought us here today. Our ancestors were similar to animals. We used to hunt to feed our stomach. We stayed in caves or trees.
Gradually, nature gifted us different qualities that are not seen in any animals till now. Being able to communicate through a language, upright walk, and a powerful brain differentiates us from other animals.
The study of living beings holds some interesting biological facts about the human body. Read on to know more about the human body, an intriguing part of mankind. Nothing would be possible in this world if our body doesn’t perform in the way that it performs today.
Here are some important facts to know about the human body which are worth knowing for your kids.
The Human Brain is Bigger Than a Dinosaur’s Brain
You must be wondering that dinosaurs were enormous when they were alive. Yet, their brain was a tiny part of their body. It often weighed only one-thousandth of their enormously huge body mass. In contrast, humans’ brains are one-fifth of their average body mass.
The weight of the human brain is about 1.4 Kg.
The human brain was not the same from the beginning. Our ancestors had small brains back then.
Due to the evolution of their body, their brain gradually became bigger too! With the evolution of sizes, the brain became sharper and innovative.
It was a turning point and led to the beginning of humankind.
An Adult Body Contains Five to Six Litres of Blood
Our body has blood to transfer millions of important cells along with water. And not only cells, but it also helps transport oxygen to the entire body.
As you know, oxygen is vital for surviving. Without blood, it wouldn’t be possible to transport it to every organ present. It extracts the waste products from our body, turning them into carbon dioxide. This keeps the blood clean and healthy.
Human blood is red, and an adult’s heart pumps almost around 7000 litres of blood every day!!
One other Interesting and important Fact to Know
Octopus’ blood’s colour is blue. Their bodies have copper, which turns the colour of their blood into blue rather than red.
Our Small Intestine’s Villi will Spread to an Area of Almost Three Large Apartments!
The simple work of a small intestine is to digest food and carry it over to the large intestine. Its length is very long, which makes the food stay for more time. This, in turn, helps the body digest the food properly.
Villi is present in the inner wall of the small intestine. It helps the small intestine absorb the primary nutrients for the bloodstream. Villi are tiny in size, but the function it performs is essential for our body.

Blood helps doctors identify tons of infections as almost every nutrient and microbes flow in it.
Millions of New Cells are Formed in the Human Body Each Second
About 25 million new cells are regenerated each second inside the body. This helps in removing unwanted cells from the body and keeps them away from disease.
