A. It increases...let me explain. Normal time between inspiration end expiration, is determined by the triggering of the peumotaxic center in the medulla oblongata (reticular substance ventral or anterior to the floor of IV ventricle) as CO2 builts up, there is a "breaking point" in which the chemorreceptors in the brain, discharge, and then, inspiration comes...this is in normal circumstances, breathing at rest Suppose now, you breath forcibly deeper and faster? The CO2 in the blood wil decrease, because most of it, will be gone momentarily with the exhalated air...so it takes longer to stimulate the chemoreceptors in the medulla oblongata, carotid bifurcation, aortic wall, etc. because you need good 3-4 minutes to "rebuild" or build up… [cont.]

Flight-duration differences between flights and return flights?
Q. If you fly from London to New York will the duration of the flight be longer, shorter or the same as when you travel from New York to London..If there is a difference how is it explained?What about other geographical areas? (After alot of thinking I concluded that earth's rotation should not be the reason because the airplane has the speed of the earth already and therefore earth could be taken as a system of inertia...but then again I might be wrong).Something about the wind currents maybe? Please don't guess and answer only if you are confident that you know the correct answer.
