  We have investigated the non-static Lorentzian Wormhole model in presence of
anisotropic pressure. We have presented some exact solutions of Einstein
equations for anisotropic pressure case. Introducing two EoS parameters we have
shown that these solutions give very rich dynamics of the universe yielding to
the different expansion history of it in the $r$ - direction and in the $T$ -
direction. The corresponding explicit forms of the shape function $b(r)$ is
presented.We have shown that the Einstein's field equations and unified first
law are equivalent for the dynamical wormhole model. The first law of
thermodynamics has been derived by using the Unified first law. The physical
quantities including surface gravity and the temperature are derived for the
wormhole. Here we have obtained all the results without any choice of the shape
function. The validity of generalized second law (GSL) of thermodynamics has
been examined at apparent and event horizons for the evolving Lorentzian
wormhole.
