Abstract: Complex dynamical model of the closed cardiovascular and respiratory systems including their interaction is considered in this work. An approach is proposed to substitute single-component model of the alveolar volume with multi-component model. Improved structure of the vascular network based on the experimantal data is represented. Resonance propertires of the alveolar volume are stadied using the proposed multi-component approach. Numerical results are represented showing oxygen concentration decrease in pulmonary circulation depending on the amplitude of the disturbances affecting the alveolar volume on its eigenfrequencies.
