ELT-63306 Modeling of Physiological Systems,
Exam 26.11.2013

1. Describe three different uses of computational model in medicine. Give examples as well

2. a)Compare Empirical model (black box model) versus theoretical model. How these
modeling methods work in modeling physiological systems?
b) Figure below is measurement of lung volume as function of pressure. Describe how you
would use the data to build a black box model? Is it possible to build other kinds of models
using the data?

3. In the picture above right there is a FEM computational flow model of the blood pulse in
aorta (deformation+ pressure in grey scale). Describe a) how this kind of model can be
constructed (what data needed), and b) what kind of boundary conditions are reguired to
solve this model?
