The FVC is the amount of air that you can take on in one great big breath in and force out to maximum exhalation. The FEV1 is the amount of air that is forced out in the first second.

FVC: forced vital capacity, is the maximum volume of gas that can be exhaled ads forcefully and as rapidly as possible after a maximal inspiration.
FEV1,Forced Expiratory Volume, the normal adult exhales 83 % or more of the FVC in one second, most common pulmonary functions, to test for the severity of an obstructive pulm disease and distinguishes between an obstructive and restrictive lung disorders
often shown as a (FEV1/FVC ratio)
hope that helps

FVC is the forced vital capacity, or the volume of gas that a person can exhale forcefully from a maximum inhalation to maximum exhalation (this is pretty much the same as the vital capacity).
FEV1.0 is the volume of gas a person can exhale in the first second, starting from maximum inhalation. It is a measure of how quickly a person can get rid of air in their lungs.
FEV1.0 / FVC should be 0.75 or greater, and is decreased in obstructive lung disease. In restrictive lung disease, FVC is decreased, so the FEV1.0/FVC ratio usually appears normal or increased.

Same as the above.
