Adults normally breathe about 500-700ml of air at a time. An average 14 year old takes around 30,000 breaths per day. Breathing is in most cases executed by one nostril at a time instead of two, and the nostril in use changes after a period of time that can be every fifteen minutes or upwards of 3 hours depending on the individual.
The air we inhale is roughly 78% nitrogen, 21% oxygen and 1% argon, helium, carbon dioxide, other gases and 1% Water Vapor.

Normal air is 21% oxygen and we exhale about 17%, thus we only use about 4%.
