About 20%% of the air we breath is oxygen. The PaO2 (oxygen breathed in mmhg) is approximately 100 mmhg.

What do humans breathe out and plants breathe in?
They breathe in carbon dioxide and breathe out oxygen. That's how they help us. It's called photosynthesis, requiring the use of the sun and CO2. It produces sugar, energy, and O2.
What do you need to breathe in and out?
You need to breathe in oxygen and you need to breathe out carbon dioxide.
You breathe out the same amount of nitrogen as you breathe in Why is this?
because the haemoglobin present in our blood has no capacity to absorb nitrogen so the result is that the nitrogen is not absorbed and you breathe out the same amount of nitrogen as you breathed in.......
What does respiration remove from the atmosphere?
Carbon dioxide is being released. As you breathe in you inhale fresh oxygen, but as you breathe out your body releases carbon dioxide.
What are the differences between the surrounding air and exhaled air?
The air you breathe out is little changed from the air you breathe in, except that the oxygen content is somewhat lower - your body extracts some (not all) of the oxygen. The exhaled air is the same except for slightly lowered oxygen content.
Do you breathe out as much oxygen as you breathe in?
Yes the same amount will leave you as you take in on average but when you breathe out there will be more CO2 and less oxygen as your body uses Oxygen for it's metabolic functioning and releases CO2 in it's place. So yes same amount out as in but in a different form.
When exercsing how much oxygen do you breathe out?
The same amount you wil just breathe in more often
What gas do we breathe small amounts of it out?
We breathe out the nitrogen and the oxygen in the air - though the amount of oxygen that goes out is less than the amount that goes in, since part of it is absorbed by our lungs.We also breathe out carbon dioxide, which is a result of our metabolism.
Do you breathe in or breathe out oxygen?
Humans breathe in oxygen and breathe out carbon dioxide. Trees "breathe" out oxygen.
Why is it harder to breathe he higher you go?
Because - the higher up the atmosphere you go - the less oxygen is in the air you breathe. Our bodies need a certain percentage of the air we breathe to be Oxygen - reduce the amount of oxygen in each breath, and it soon affects the body.
What is the process of water and oxygen combination?
A certain amount of oxygen dissolves in water (thus enabling fish to breathe).
Why do you breathe faster after running hard and after playing hard?
Breathing is when your body is getting oxygen to your cells. When you are physically active your cells use the oxygen faster so you have to breathe faster to get the same amount of oxygen to your cells
Do humans breathe out only carbon dioxide or carbon dioxide with a little amount of oxygen?
we breath out a little oxygen aswell
Do you breathe in oxygen?
Yes you do. See we breathe in oxygen and we breathe out carbon dioxide. Plants are the opposite. They breathe in carbon dioxide and breathe out oxygen. We give them carbon dioxide and they give us oxygen!! That's how we breathe!!!!!!!
What is tidal lung capacity?
Tidal capacity is the amount of oxygen the lungs can breathe in and out per breath
How many percent of oxygen did you breathe?
You breathe out 16.3% oxygen.
What do you breathe when you breathe out?
Humans breathe out carbon dioxide, the whole world runs in a motion, for example plants breathe carbon dioxide, we breathe in oxygen. Even fish breathe oxygen. They take the oxygen out of the water. So we breathe in what plants breathe out and plants breathe in what we breathe out.
