Neurological and humoral control of blood pressure.

Abstract

Systemic arterial blood pressure, flow and blood volume are closely regulated by a group of interrelated mechanisms. Perhaps the most important mechanism in the moment-to-moment control of arterial blood pressure is the arterial baroreceptor reflex. This reflex influences blood pressure by modifying a series of cardiovascular parameters: heart rate, cardiac stroke volume and peripheral vascular resistance. The key to understanding how the arterial baroreceptor reflex controls blood pressure is the interrelationship between these parameters.
