Definition

Blood pressure is controlled by several feedback mechanisms. The fastest one baroreceptor reflex (baroreflex) can be defined as the biological neural control system responsible for the short-term blood pressure regulation.

From modeling perspective the baroreflex feedback control system consists of three parts (Fig. 1):
