In my biology book it says 78% nitrogen is inspired air and 75.40 Expired, but the actual volume of nitrogen inspired and expired is the same... So why say that tge percentage volume inspired and expired is different?
Also why is the actual volume of inspired and expired Nitrogen the same?
This is NOT my homework...

Your talking about Human Respiration... right?
Well as you said there is no difference in inhaled and exhaled air, because as you know nitrogen can not be used in gas form by the body.
The reason for the difference in percentage is just because it is a percentage of the total. As the oxygen and carbon dioxide figures change it alters the mathematical percentage of nitrogen. However it is purely mathematical and not actually a change in quantity.
Danke Schon.

You also expire water vapor which as not present in the inspired air.
The nitrogen volume remains the same because there is no mechanism to actively capture it, and that nitrogen in your blood and in the air is at equilibrium for a given constant environmental pressure (which is not the case when divers come back from deep underwater, hence the decompression process needed to progressively vent out dissolved nitrogen).

there is not any distinction in inhaled and exhaled air as nitrogen can't be used in gas style by technique of the physique. the clarification at the back of the version in share is purely because of the fact that could be a share of the finished. because of the fact the oxygen and carbon dioxide figures substitute it alters the mathematical share of nitrogen....besides the undeniable fact that that is purely mathematical not an actually quantity substitute! wish this facilitates
