What percentage of the air you breathe into your lungs is actually used by your body to function normally?
About 21% of the air you breathe in is oxygen, which is used by your body to function normally. The rest is made up of mostly nitrogen and trace amounts of other gases.
Why CO2 is more in alveolar air than expired air?
CO2 is more concentrated in alveolar air compared to expired air because gas exchange occurs in the lungs where oxygen is taken up by the blood and CO2 is released into the alveoli. Additionally, more CO2 is produced in the body through cellular respiration, contributing to its higher concentration in alveolar air.
