In the electric analogue the ascending (descending) aorta section is modelled with 4-MW elements Laa, Raa, RVaa and Caa ( Lda, Rda, RVda and Caa ), carotid arteries compartment is represented with a single resistance (Rca). Peripheral arteries section is reproduced with 3-MW elements (Ra, Ca and RVa), the flow is devided in Qa and QRVa. The systemic veins compartment is modelled with 4-MW elements (RVvs, Rvs, Lvs and Cvs). The blood flow into vena cava bed is (QRVaa+QRVda+Qvs+Qvc).
