Vascular Organ Blood Flow Regulation!

Which of the following is not correct regarding the regulation of blood flow in organs?

A) During exercise increased delivery to the muscle is accomplished by increased blood flow and increased O2 extraction.
B) In coronary circuit, increased flow is essential to meet tissue O2 demands during exercise.
C) A-V PO2 difference is larger in renal circuit than coronary circuit.
D) The A-V PO2 difference is increased in exercising muscle.
E) Assuming no effect on metabolism, a vasodilatory drug causes a decrease in PO2 A-V difference in resting muscle.
F) α1 agonists can increase PO2 A-V differences in arterioles.
G) If PaO2 increases from 97 to 100, the blood flow to the brain would not be changed significantly.
