Exhaled air contains 16% oxygen and 21% when inhaled.
21% is the air you breathe.
Inhaled air contains more oxygen than carbon dioxide and other gases. Exhaled air contains mostly carbon dioxide as the inhaled oxygen was used up to create energy. Waste carbon dioxide (and other unwanted gases) is then let out of the body and the cycle continues. :)Gas exchangeGas% in inhaled air% in exhaled airOxygen2116Carbon dioxide0.044Nitrogen7979
You have about 20% oxygen in inhaled air and negligible carbon bi oxide. You have about 4% carbon bi oxide in the exhaled air. That means 4% of the oxygen is absorbed from the blood. That makes it 4%/20%= 20% of the oxygen from the inhaled air is absorbed in your blood.
Air contains about 21% oxygen, so the candle in air might only burn 21% as long as a candle in oxygen. Of course, that does not include other variables, like the candle burning in oxygen will burn hotter, melting the candle wax sooner.
Air inhaled through the mouth is not as clean as air inhaled through the nose. Reason for this is that when we inhale air through our nose than it get filtered by hair present in our nose. But air inhaled through our mouth goes directly in without any filtration.

The concentration of oxygen inhaled depends upon the prescribed flow rate and the ventilatory minute volume (MV).

Exhaled air has more carbon dioxide and less oxygen than does inhaled air.
21% of the air we inhale is oxygen
Inhaled air contains more oxygen than exhaled air because the cells have not yet used that oxyginated air.

Inhaled air is richer in oxygen than exhaled air.

It is because, once the air is inhaled, the lungs absorb the oxygen in the air and releases only the remaining stale air. The air that goes in has a higher % of Oxygen and the air that comes out has a higher % of Carbon di oxide.
Inhaled air contains a greater volume of oxygen than carbon dioxide. Exhaled air is the opposite, since after the exchange of gases in the lungs the carbon dioxide in the blood is transferred into the lungs. Exhaled air contains a greater volume of carbon dioxide than oxygen. Also, there is more water vapour in exhaled air than inhaled air.
Exhaled air has less oxygen than inhaled air.Exhaled air has more carbon dioxide than inhaled air.Exhaled air is warmer that inhaled air.Maybe the first 2 are redundant, but I think that should work!
