We exhale more oxygen than we use. Air contains approximately 20% Oxygen - when we breathe in - we absorb about 4% of the oxygen - and exhale the rest.

What take oxygen that your body needs from air and put it in your bloodstream?
The lungs are part of the respiratory system that with the circutory system add oxygen to your blood.
From where does the blood get oxygen?
The blood gets oxygen from the air around us which is made of oxygen. When we breath in, the oxygen is taken into our lungs and then into our blood.
People breathe in oxygen molecules from the air and exhale carbon dioxide molecules. Because of this the air is full of carbon dioxide and oxygen mixed together. What is this an example of?
an increase in entropy
Where do lungs get oxygen?
yes they both do but mostly fish use gills.
How does oxygen enter your body?
Oxygen (O2) enters your body through breathing air, which contains oxygen in it. This oxygen goes into your lungs where it is put into the bloodstream, supplied to cells in your body, returned to the lungs as carbon dioxide (CO2), and exhaled through the lungs.
What is the of air into and out of your lungs?
oxygen goes into your lungs and then co2 comes out when mixed with a substance in your lungs.
When the lungs inhale oxygen what does it exhale as a waste?
The lungs largely exhale carbon dioxide and water vapor along with the non-oxygen components of the air taken in (such as nitrogen).
Do we exhale to remove oxygen from the lungs?
No - we exhale to remove air that has a high content of carbon dioxide. Excess oxygen is not a problem when breathing - oxygen deficiency IS a problem.
How can you breathe through your mouths and nose?
Your lungs circulate oxygen every time you inhale and exhale. They travel through your body when you inhale to the lungs and the lungs store the oxygen, and as you exhale, carbon dioxide from the air is released.
Do we exhale to remove excess oxygen from the lungs?
No - we exhale to remove air that has a high content of carbon dioxide. Excess oxygen is not a problem when breathing - oxygen deficiency IS a problem.
How do alligators obtain oxygen?
Alligators are air breathers. They inhale and exhale through their nostrils. Their lungs absorb oxygen from the air that they inhale.
What are the place where the oxygen rich air enters the body?
Oxygen rich air enters the body through the lungs.
Where does blood get a new suppy of oxygen?
From the lungs. In the lungs of animals, humans included, there is an interchange of oxygen for carbon dioxide. So we inhale oxygen(air) and exhale carbon dioxide.
Does all the air in the lungs get change with each breath?
All of the air in the lungs gets exchanged with oxygen upon each breath. We exhale carbon dioxide and inhale oxygen.
Do inhale or exhale when the gases inside the lungs are pushed out through air passages?
You exhale because you're body is getting rid of the gases so the oxygen can come into your lungs.
What is the air chambers inside an animals body where blood get oxygen and give off carbon dioxide?
It is the lungs. it is there it is simple. when one breathes you inhale oxygen when you exhale you exhale carbon dioxide
I don't understand how CPR works we breathe in oxygen and we exhale CO2 so how come during CPR when we breathe into the person we are exhaling CO2 into there body insted of oxygen?
Atmospheric air has about 20.5% oxygen and our lungs only extract about 4.5% oxygen, so the air we exhale has about 16% oxygen, 4.5% CO2. The air we breathe into the victim then has 16% oxygen for their lungs to extract oxygen from.
