Carbon dioxide is a waste product of respiration and moves by diffusion in the other direction. It moves from the cells into the blood and then from the blood into the lungs before it is breathed out.

Red blood cells collect carbon dioxide from the body’s cells and transports it back to the lungs. An exchange of oxygen and carbon dioxide takes place in the alveoli, small structures within the ...

Doctors use lung diffusion tests to measure how well a person’s lungs exchange oxygen and carbon dioxide. The test can detect lung damage and help diagnose lung conditions, including emphysema ...

Carbon dioxide emissions from fossil fuels are changing the Hadley cell, an atmospheric circulation that influences the weather and can make more places turn into deserts.

Fortunately, to balance this out, CO2 is dissolved into the oceans (though it is interesting to note that about 93% of the worlds CO2 is actually contained within the oceans.) ...

THE barium oxide–carbon, dioxide system has been examined at pressures of carbon dioxide up to 450 atm.1 and is similar in many respects to that of calcium oxide and carbon dioxide2. To bring ...

If your doctor needs to figure out why you're having trouble breathing or to check for other lung problems, they may suggest lung diffusion testing.It measures how well your lungs are working ...
