Humans breathe in air, which contains both oxygen and carbon dioxide. Butwe do not photosynthesise and so wedo not take in CO2. The CO2 produced from respiration in our body builds up in the blood and through diffusion escapes into the lungs and out whenwe exhale.
body will take only thoses gases which is useful to body and their parts only..
