Yes, When one expires there remains an amount of residual oxygen left in our lungs in order to maintain the pressure difference in our respiratory system. So when one holds his breath for some time, exchange of gases takes place with the residual gas.

Yes there will be there be exchange of gases in the lung sif one holds his breath after expiration for about 30 seconds, An equilibrium exists in between gas dissiolved inside the blood of our body and the gas present in the alveolae. This is referred to as Henry's law. So amount of gas dissolved is proportional directly with the pressure of gas partially over the liwuid.
