Effect of Elevation of Intraluminal Pressure on Renal Vascular Resistance

BUltTON and colleagues' suggested recently that stretching the venous wall in limbs elicits a local reflex resulting in constriction of local arteriols. They felt that this "veni-vasomotor" reflex supplemented the central buffer reflexes in controlling blood flow through extremities during change in posture. Utilizing methods permitting direct measurement of small and large vessel resistance in the dog foreleg, Haddy and Gilbert independently reached a similar conclusion, except they felt the reflex was not necessarily local.
