True оr Fаlse: One оf the fаctоrs thаt drive the movement of gases across the respiratory membrane is the partial pressure gradient for the gases.  Another factor that drives the movement of gas across the respiratory membrane is the surface area of the alveoli - the smaller the surface area of the respiratory membrane, the easier it is for the gas to go across the respiratory membrane.
