Hyperaemia in skeletal muscle during exercise is normally associated with

A. False   Exercise hyperaemia occurs normally in sympathectomized muscles.

B. False   True capillaries have no smooth muscle; they dilate passively with the rise in capillary pressure due to active arteriolar dilation.

C. False   Arterial pressure usually rises.

D. True   Vasoconstriction in kidneys, gut and skin prevent excessive falls in total peripheral resistance.

E. True  This, together with the reflex constriction above, compensate for the fall in muscular vascular resistance and thus prevent arterial pressure falling during exercise.
