Answer 2

Hi Riya !!!

Here is your answer . . . . . .

The differentiation is not done by the nose but is done by the lungs which utilises the oxygen inhaled along with other gases and exhales the carbon dioxide gas along with other gases which are not used by the human body. The exhaled air also consists of small proportion of oxygen because our body cannot used the whole oxygen inhaled through our nose.
