What is the volume of air in out lungs?
In total, the average mans lungs can contain 5800ml of air and
an average womans lungs can contain 4050ml of air, however, it is
only possible for a man to forcefullly exhale 4600ml of this air,
and a woman can only forcefuly exhale 3150ml. If the remaining air
were to be removed from the lungs they would collapse.

Medical Physiology" 2006 Ed.
In normal rested breathing, an average male breaths in and out
500ml of air, and an average women breaths in and out 350ml of air.
This volume is called the tidal volume.
If an average man were to forcefully inspire as much as
possible, he could breath in an additional 3000ml of air. An
average women could forcefully breath in an additional 2000ml. This
additional volume that can be inspired is called the inspirational
reserve volume.
If an average man were to forcefully expire as much air as
possible, he could push out about 1100ml of air in addition to the
normal 500ml. An average women could forcefully push out an
additional 800ml. This additional volume that can be exspired is
called the exspirational reserve volume.
There is an additional 1200ml of air in an avergae mans lungs,
and an additional 900ml of air in an avergae womens lungs that they
cannot blow out. This volume is called the residual volume.
