Do you use all the oxygen you inhale?

Best Answer

You breath in oxygen which is O2

What is exhaled is CO2 or carbon dioxide.

The reason for this is the human metabolism is based on the reaction between Glucose (C6H12O6) and oxygen gas (O2). The oxygen reacts with the glucose to produce carbon dioxide and water to release energy for out bodies to use.

6O2 + C6H12O6 --> 6CO2 + 6H2O + energy

We need to get rid of the carbon dioxide because it is toxic.

The water produced is of little consequence as our bodies are mostly water anyway.

oxygen is one component of air, it makes up 22% of the volume of air. nitrogen makes up 77%. living things require oxygen in the proccess of respiration, which allows us to create energy. we inhale oxygen, it is absorbed by our lungs into our bloodstream, which trasports the oxygen to ourselves where respiration occurs.

We breathe in air which is actually a mix of many different gases. Oxygen is the portion of the air that is absorbed through our lungs into our blood stream.

The reason why the body has so much oxygen is because it is needed for all of its organs like the heart, lungs, and brain. A lack of oxygen also can cause respiratory failure.

You have to breathe in something! Oxygen + Carbon Dioxide = Glucose and water

Glucose is a form of sugar and gives the body energy.

You mainly exhale nitrogen and a little carbon dioxide.

Air contains about 21% oxygen and 79% nitrogen (with a very small percentage of inert gases). Therefore, with each breath, a significant amount of oxygen is inhaled.

At sea level, most of the oxygen that you breathe in gets exhaled right back out. This is about 80 percent of it.Only 20 percent of it gets absorbed by most people.

No, you use only a small portion of the oxygen you inhale. that is why you can blow into the mouth of someone who is not breathing and help them to breath on your exhaled air.
