Yes. Though the air you're breathing might not exactly be 'fresh,' you do get a fresh supply with every inhalation.

I enter your blood with each breath of fresh air What am I?
Oxygen flows into your blood when you breath April:)
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.
Why isn't it correct that we breathe in only oxygen and breathe out only carbon dioxide?
Because when you breath, you breath air which is 80% nitrogen and 20% oxygen. Also the air you breath out still has oxygen in it, you do not use all the oxygen and only produce a small amount of carbon dioxide in each breath.
Is the amount of oxygen in each breath less at high altitude?
yes
What enters your blood with each breath of fresh air?
The diaphragm squeezes the air out of your lungs
Which animals and plants depend on each other?
All of them. The plants turn the carbin dioxide converted by you into oxygen and then you can breath. You then, when you breath out, give out more carbin dioxide for the plants to breath, and give you more oxygen, Etc...
How does how fast you're breathing affect cellular respiration?
the breathing rate and volume of each breath increases to bring more oxygen into the body and remove the carbon dioxide produced. the heart rate increases, to supply the muscles with extra oxygen and remove the carbon dioxide produced.
Why isn't the oxygen in the earths atmosphere is not used up by the breathing of humans and other animals?
As you breath in oxygen your body exchanges it for carbon dioxide which is the air you breath out. As you and all other oxygen breathing animals do that, the earths plants to the opposite they breath carbon dioxide and release oxygen. That is why it is important to protect the worlds plants. We need each other.
What happen to the air you inhale?
It goes through your respiratory system, and into the blood stream, where the oxygen takes the place of 'old oxygen', which has been converted to carbon dioxide, and you breath out the carbon dioxide. That is repeated with each breath.
Why is it more difficult to breath on mountains than on plains?
At higher altitudes, the air pressure is lower. Therefore each breath you take contains less oxygen.
What is the function of a birds air sacs?
Can obtain more oxygen from each breath of air
What happens to carbon dioxide produced during the Krebs cycle?
The CO2 produced by the Krebs cycle is a waste product; it is disposed of as waste. In humans, we breath in oxygen with our lungs, use that oxygen in cellular respiration, and breath out the waste CO2. It should be noted that air is not made entirely of Oxygen and carbon dioxide, and that our bodies are not efficient enough to consume all of the available oxygen in each breath, and that therefore, what humans exhale is not 100% CO2.
