1. A tissue block for simulated surgery, comprising:
isolated animal tissues harvested from more than one animal;
one or more of an adhesive and fastener adhering together the isolated animal tissues into at least one simulated human organ for simulated surgery; and
a salt-containing hydrogel formulation contained within the at least one simulated human organ, said salt-containing hydrogel formulation having salt in an amount sufficient for electrocautery, said salt-containing hydrogel formulation adding viscosity to the at least one simulated human organ.
