In the slide are plotted different cardiocirculatory sections with TAL. Heart section consists of left and right ventricles, left and right atria and the septum. All these elements are described by variable elastance model; elv (erv) represents the left (right) ventricular time-varying elastance; ela (era) is the left (right) atrial time-varying elastance; eV-SPT (eA-SPT) represents the time-varying interventricular (interatrial) septum (see the Numerical Heart Model (2) section). AT, TT and ABT are the aortic, thoracic and abdominal tracts respectively. SV is systemic thoracic vein section. MPA (SPA) is the mean (small) pulmonary artery section. PA (PC) is the pulmonary arteriole (capillary) section. MV, AV, PV and TV are the mitral, aortic, pulmonary and tricuspid valves respectively. TAL section is described by: LTALin, LTALala and LTALan modelled the inertia in the grafts (they depend on the blood density, the graft radius and the graft length; CTALad (CTALap) represents the TAL inlet (outlet) chamber; CTALin (RTALin) is the inlet compliance (resistance) of the TAL; RTALpab and RTALala are two resistances used to divide the flow between the pulmonary artery (RTALpab) and the left atrium (RTALala); RTALad (RTALap) are the flow dependent inlet (outlet) resistance; RTALan is the outlet graft resistance to the pulmonary artery.
