Baroreceptor mechanisms and the control of vascular resistance
Animal studies have documented that arterial baroreflexes subserve crucial functions in cardiovascular control. First of all, arterial baroreflexes minimize moment-to-moment blood pressure oscillations , thereby reducing the extent of spontaneous blood pressure variability and its possible impact on cardiovascular disease . Secondly, they participate in the cardiovascular modulation of a number of behaviours (sleep, exercise,, emotion, etc.), ultimately determining the size of their heart rate and blood pressure effects [3, 4]. Thirdly, arterial baroreflexes may be important in the long-term determination of mean blood pressure levels, as shown by the sustained rise in blood pressure that has been reported to follow chronic section of the carotid sinus and aortic nerves .
