It is shown that the truncation of the infinite hierarchy of fluid
equations obtained
as moments of the Vlasov kinetic equation leads to a system of nonlinear
equations
that describe finite-Larmor-radius effects with good accuracy. Inertial
terms in the
momentum balance, viscosity and heat-flux evolution equations are crucial
for a
uniform description of the plasma response with an arbitrary Larmor radius.
In
the low-frequency ordering, the obtained equations are simplified by an
expansion
in the parameter 1/B, where B is the
equilibrium magnetic field. The results of
the second-order [Oscr ](1/B2) and the
fourth-order [Oscr ](1/B4) closures are compared.
It
is shown that the accuracy of the description improves for higher-order
closures.
