Role of baroreceptors in the zone of vertebral arteries in the reflex regulation of venous tone in the splanchnic basin.
Pressure elevation in the reflexogenic zone of vertebral arteries was accompanied by a decrease in the tone of splanchnic veins, reduction of blood pressure, and suppression of external respiration. An opposite response of the cardiorespiratory functional system was observed under conditions of low baseline pressure in the vascular zone. Our findings and results of previous physiological and morphological studies indicate that the capacitance vessels play an important role in cardiorespiratory reactions.
