Nitrogen is part of DNA as well as being incorporated into every amino acid used by the body.
The roots extract nitrogen from the soil.
In terms of the human body, bioelements are any compounds or molecules that make up the body and help it with various functions, such as breathing. Some of these bioelements include: oxygen, nitrogen, and calcium.
The Digestive System breaks down the materials and uses them later on in the body function
negative nitrogen balance.
Positive nitrogen balance
Nitrogen is a necessary part of all protein molecules and therefore, it is part of all biochemistry.
nothing, absolutely nothing, nitrogen gas is 70% of the earth's air, it enters our body 30% and goes out 30%.
Nitrogen is an absolutely essential part of amino acid structure, which makes up protein. Organisms are essentially "made" of protein, that is, the structure and function of their bodies is thanks to proteins. Nitrogen also has many other uses in the body such as the synthesis of non-protein nitrogen products (Nitric oxide, a vasodilator, and GABA, a neurotransmitter just to name a few.) But protein is definitely the most important function of Nitrogen. (Thanks to Jen for this answer!)
What is the function of nitrogen
it goes through your body and comes out as carbon dioxide. trees use the carbon dioxide to make more nitrogen that you breathe again.
There a number of important elements that the body uses: C,H,N,O,P, S (CHNOPS). As you see nitrogen is one of these 6. The most important use is in the nitrogen bases. These include DNA and RNA. Each has a nitrogenous base. The ones in DNA code for proteins. This code is for production of an organism such as ourselves. RNA also has bases and RNA is important in the "reading" and "translation" of these bases.
The body uses proteins, lipids, and carbohydrates for energy. It uses minerals and vitamins to build substances in the body that the body uses to function. Such as iron for hemoglobin or vitamins as anti-oxidants.
Since urea is an organic compound, the body has many uses for it. The most important being the use of excreting Nitrogen. It is also used in fertilizers since it is a good source of Nitrogen.
The human body is about 3% Nitrogen
Nitrogen is used in the nitrogen cycle to help plants grow.

They go through your skin and into your bloodstream. After that your body uses it or not. Your body usually takes the minerals from it and realesses it.
