The oxygen in the air you breathe in is absorbed via the lungs into the blood.
The air you breathe out contains around 16% oxygen and 4% carbon dioxide, with the remaining percentage made up of nitrogen, water vapor, and other trace gases.
The air that we breathe in 78% nitrogen, 21% oxygen, and 1% carbon dioxide, water vapor, and other gases. We only need the oxygen though, so we breathe out the other gases with the carbon dioxide that our body produces during respiration. So to answer your question, it is nitrogen, but we breathe it in and then out- we don't use it. The only gas we use is oxygen to breathe.
The air we breathe is: about 78% Nitrogen about 20% Oxygen about 1% Argon and the rest lots of other chemicals in tiny amounts.
Concentration of oxygen in dry air is 20,946 %.
When you inhale, you breathe in air, allowing oxygen to enter your lungs. When you exhale, you breathe out air, releasing carbon dioxide from your lungs. This process is essential for the exchange of gases in your body.
What we breathe is air, and oxygen is just 20% of the air. Oxygen does not contain water, it is an element and it contains only itself. However, air does contain some water vapor.
it contains oxygen and carbon dioxiod and your mom
No, you cannot breathe air bubbles underwater because they do not contain enough oxygen to sustain human respiration.
The air we breathe out contains a lot of stuff and the list would be exhaustive, but the main components in the air we breathe out are nitrogen, oxygen, carbon dioxide, and water vapor.
Particles in the air contain oxygen, which enable us to breathe.
Oxygen is approximately 21% of the air we breathe.
Around 21% of the air you breathe is oxygen.
You blow out carbon dioxide, trees breathe it in, trees breathe out oxygen, you breathe in oxygen. It's the air cycle.
You blow out carbon dioxide, trees breathe it in, trees breathe out oxygen, you breathe in oxygen. It's the air cycle.
You breathe in air, which is comprised mostly of nitrogen (though the oxygen is what you're after).The oxygen is absorbed into the blood, and stored in red blood cells, which contain hemoglobin.The oxygen in your lungs is thus replaced mainly by carbon dioxide, which is a metabolic waste product, and this is what you breathe out.
On average, humans breathe in about 21% oxygen from the air.
Oxygen makes up about 21% of the air we breathe.
