The modeling of physiological control systems
via mathematical equations reflects the calculation procedure
more than the structure of the real system modeled, and several
simulation environment have been used so far for this
task. Nevertheless, object-oriented modeling is spreading in
current simulation environments through the use of the individual
components of the model and its interconnections to
define the underlying dynamic equations. In this paper we
describe the use of the MODELICATM simulation environment
in the object-oriented modeling of the cardiovascular control
system. The performance of the controlled system has been
analyzed by object-oriented simulation in the light of existing
hypothesis and physiological data used here for validation
purposes
