The air we breathe is made up of about 21% oxygen. Our bodies primarily use oxygen for metabolism, and the amount we need is relatively small compared to the total volume of air we inhale. The excess oxygen is exhaled to maintain a balance in the body.
Humans use their respiratory system to breathe in oxygen from the air and release carbon dioxide as waste. This process occurs in the lungs where oxygen from the air is absorbed into the bloodstream and carbon dioxide is removed from the body.
You breathe in oxygen and breathe out carbon dioxide. Inhaling brings oxygen into your lungs, which is then absorbed by your blood for use by your body's cells. The carbon dioxide produced by your cells is carried back to your lungs and exhaled out of your body.
Oxygen is important for air because it is essential for the survival of most living organisms, including humans. We need oxygen to breathe and carry out cellular respiration, which is the process our cells use to produce energy. Without oxygen, living organisms would not be able to survive.
Oxygen is a gas that we breathe in to stay alive. It is essential for the process of respiration, where our cells use oxygen to produce energy. Without oxygen, living organisms cannot survive.
All plant and animal live requires oxygen to survive
Animals do not use up all the oxygen in the atmosphere because plants produce oxygen. When they breathe, plants inhale carbon dioxide (which is what animals breathe out) and exhale oxygen (which is what animals breathe in).
No, not all the oxygen you inhale is used by your body. About 20% of the oxygen we breathe is used by the body for energy production through respiration, while the remaining 80% is exhaled back out into the atmosphere.
We breathe in oxygen and breathe out carbon dioxide. Plants take in this carbon dioxide and release oxygen, which we use after that.
Animals breathe in oxygen in the air.
To Breathe.. You Use Your Lungs To Breathe In Oxygen And Breathe Out Carbon Dioxide.
so you can breathe
They use them to breathe with, to get oxygen from the air.
if u r talking about mouth-to-mouth respiration, you might be wondering, the person exhaling have used up all the oxygen in the air, so why does the inhaling person can still get oxygen? The answer is, actually we cannot use up all the oxygen in the air we breathe in. There is approx. 21% oxygen in the atmosphere (i.e. in the air we breathe in), but in the air we breathe out, depending on our activity level, will have 4-5% less oxygen. Therefore we actually still have around 16% of oxygen in the air we breathe out. Therefore the person helped with artificial respiration can use this oxygen
Great Whites - like all Sharks - use gills to filter oxygen from the water. They can't breathe air.
to breathe
All fish breathe through their gills. Some have additional organs to assist but all fish use their gills to obtain oxygen from the water they live in.
Terrible grammar. Either the asker does not speek English or is mentally challenged. I will slowly answer this question the best that I can. Humans... use oxygen... to breathe... If humans could not breathe they could not do anything industrial! That is "how humans you use oxygen in industry". They breathe it. You should try it. Your brain could use some oxygen numbnut!
