There are various elements in our body, and it is precisely because of the existence of these multiple elements that we can survive so healthy.


Scientists have done a scientific theoretical study on the proportion of iron in the human body, and have drawn an amazing result. If we collect all the iron in our body, we can probably create a 4 cm long nail.

Are you surprised by the result?

In fact, the reason why there are so many iron elements in our body lies in our blood. The reason why the blood in our body will appear red is due to the hemoglobin in our body, which is a cell containing iron. When our red blood cells carry oxygen to flow in blood vessels, the iron element in our hemoglobin is oxidized to appear red, which is why our blood is red.

We have a lot of hemoglobin in our body. Once the iron element in these proteins is raised, we can make a four centimeter long iron nail.
