In chloralose-anaesthetized dogs, pressure applied to coronary, carotid and aortic baroreceptors were changed independently and the resulting reflex vascular responses were determined. Increases in pressure to each group of baroreceptors resulted in reflex vasodilatation; the maximal responses to di...
