What is nitrogen in the air used for in your body?
Your body is not capable of directly using the nitrogen in air. It is ultimately the source of the nitrogen in the proteins and other nitrogen-containing compounds in your body, but the precursors for these are (mostly) made by nitrogen-fixing bacteria in the soil and then incorporated into molecules by plants. (The "mostly" is because some of the nitrogen used by plants comes from nitrates or ammonia applied as fertilizer.)
Why doesn't our body use nitrogen?
Nitrogen is primarily used by the body to build proteins and nucleic acids, but our bodies do not have a direct physiological need for elemental nitrogen gas. The nitrogen in the air we breathe is not in a form that our bodies can readily utilize for metabolic processes.
How do humans get nitrogen they need?
By eating plants
What is the relationship of the amount of nitrogen retained in the body to the amount of nitrogen absorbed is called of protein?
The relationship between the amount of nitrogen retained in the body and the amount of nitrogen absorbed is known as protein balance. When the body retains more nitrogen than it absorbs, it is in positive protein balance, which is important for growth and repair. Conversely, negative protein balance occurs when the body loses more nitrogen than is absorbed, often seen in conditions like starvation or muscle wasting.
What are the effects of too much nitrogen in a body of water?
Nitrogen has no effect on water although it can be dissolved. Nitrogen is not hazardous in itself, and in water is not dangerous. However as your body has no use for it when breathed, it can asphyxiate. But in water it has no effect on large biological organisms. High nitrogen content can cause algal blooms in surface areas of water. However, nitrogen can be processed into nitrates by bacteria which can kill fish. Excess nitrogen is removed by humans through urea.
Does the air we breathe out contains more or less nitrogen?
The air we breathe out contains less nitrogen than the air we breathe in. When we inhale, we take in oxygen and other gases, including nitrogen. When we exhale, we breathe out carbon dioxide, which has replaced some of the nitrogen we inhaled.
How much nitrogen in the body?
The human body is about 3% Nitrogen
How nitrogen dilutes the effects of oxygen?
nitrogen dilutes the effect of _______ in the air
What are the effects of nitrogen?
dilate vessels
When an organism dies the nitrogen in its body do what?
the nitrogen in its body is released by the action of decomposers
When nitrogen taken into the body exceeds nitrogen losses a person is in?
When nitrogen intake exceeds the body's nitrogen losses, a person is said to be in a state of positive nitrogen balance. This can occur during times of growth, pregnancy, or recovery from illness. It indicates that the body is using nitrogen to build and repair tissues.
What is the prognosis for a patient with nitrogen narcosis?
When a diver returns to a safe depth, the effects of nitrogen narcosis disappear completely. Some evidence exists that certain divers may become partially acclimated to the effects of nitrogen narcosis with frequency.
What does nitrogen do to the human body?
Nitrogen is important as it essential in any amino acid and therefore the production of proteins, allowing humans to grow and repair themselves. Nitrogen has to be ingested via plant/animal materials, breathing in nitrogen, which is abundent in the Earth's atmosphere has no beneficial or negative effects.
What is the important role of nitrogen in the human body?
The human body needs nitrogen for the proper digestion of food and growth. Nitrogen is extremely important in the development of the human fetus.

What are some of the direct effects of acid rain on humans?
There are no direct effects of acid rain on human health. However, the pollutants that are sources of acid rain, such as sulfur dioxide and nitrogen oxides, can often irritate and even damage the body's lungs.
Does the human body contain nitrogen?
Yes, all organisms need nitrogen because part of the nucleotides of nucleic acids (DNA and RNA) is a "nitrogeneous base", which is essential for life. Nitrogen is also present in many organic compounds, including proteins and nucleic acids. By mass nitrogen is the 4th most abundant element in the body.
