We establish the consistency of the Fermi liquid description and find a relation between the Fermi liquid constants for a two-dimensional electron system near the point of full polarization due to a parallel magnetic field H. Our results enable us to predict connections between different thermodynamic properties of the system. In particular, we find that near the point of full polarization ${H}_{c},$ the thermodynamic compressibility of the system experiences a jump with a subleading ${(H}_{c}ensuremath{-}{H)}^{1/2}$ dependence on the magnetic field. Also, the magnetization has a cusp with dependence of the type $(Hensuremath{-}{H}_{c}{)+(H}_{c}ensuremath{-}{H)}^{3/2}$ at $Hl{H}_{c}.$
