ABSTRACT
The article discusses work in the field of the physiology of vasodilatation. In contrast to passive dilatation which is brought about by a decrease in constrictor substance, active dilatation reflects an increase in vasoactive substance at the blood vessel level. Active dilatation also differs from passive dilatation in that neurogenic constrictor tone is not a prerequisite for active reflex dilatation to occur. The most well known and probably the most important mechanisms capable of producing passive reflex dilatation are the carotid sinus and aortic arch buffer systems. In both of these regions are located specialized afferent receptors which respond either to vascular distension or to stretch.
