Baro-Cardiopulmonary-Chemoreceptor Negative Cardiovascular Feedback Loop. Med, medulla oblongata; CIC, CAC, VMC, cardioinhibitory, cardioaccelerator and vasomotor centers, respectively; Comp, comparator; neural reference R; error signal E after the difference against the outflow from the baro, cardiopulmonary and chemoreceptors (Ba, Ca ChR), respectively. BP, blood pressure = PRxCO; Mult, multipliers; PR, peripheral resistance; CO, cardiac output = HRxSV; HR, heart rate; SV, stroke volume. P, pacemaker; CE, myocardial contractile fibers; Trans, postulated transducers from neural section to CV side. Point C, output from the baro, cardiopulmonary and chemoreceptors; Point Ek, output from the vasomotor center VMC, in the medulla. Reproduced after Ref (1).
