The vascular smooth muscle will relax, and blood vessel diameter will increase, resulting in organ blood flow being maintained at a normal level

Angiotensin II will be released, causing vasoconstriction to prevent transmission of the increase in arterial pressure to the capillary bed.

This might be caused by a metabolically driven increase in organ blood flow following vascular occlusion

The vascular smooth muscle will contract. The resulting vasoconstriction will maintain blood flow to the organ relatively constant
