A lot of comes from the air. The air you breathe is around 78 percent nitrogen, so nitrogen enters your body with every breath.
Rhizobium bacteria is present in leguminous plants in their roots which extract nitrogen from the soil. These are generally present in dicot-seed plants. When you consume these plants, nitrogen enters your body.
Another way that nitrogen enters the body is through eating meat. When animals eat plants, those plants have nitrate in them which contains nitrogen so the animals have nitrogen in them now. Then, humans eat the meat from the animals, adding some nitrogen to our bodies.
Oxygen is the most abundant element in the human body, followed by Carbon, Hydrogen and Nitrogen. Calcium is abundant, as well.
Your body needs nitrogen to make proteins in your muscles, skin, blood, hair, nails and DNA.See the related link for more information.

Most abundant elements in the human body are C, H, O, N, P, S together with some minerals Ca, Na, K, Fe and Cl.
Carbon, oxygen, hydrogen, nitrogen and traces of iron.
The human body is about 3% Nitrogen
The human body needs nitrogen for the proper digestion of food and growth. Nitrogen is extremely important in the development of the human fetus.
Urea is produced by the human body from the metabolism of nitrogen-containing compounds. Being high in nitrogen content, it is also used in fertilisers, so traces could be present on fruit and vegetables.
How does hydrogen enter the human body?
proteins
The human body stores 2.6 to 3 percent of nitrogen. The human body does routinely oxidize nucleic acids, however, the amounts of nitrogen remain within the same percentage.
Okay nitrogen is enter though the system of an animal cell
It is possible for humans to suffocate and die in pure nitrogen.
It is made up of 3% nitrogen.
Most of the nitrogen in your body is contained within proteins and most of the protein in your body is contained within the muscles.
organ system
Barbiturates enter the body orally. You can swallow, eat, and drink it.
