Hey guys,
So I know vasodilation decreases resistance, and blood pressure = blood flow (Cardiac output) x resistance
However, doesn't vasodilation also increase blood flow/stroke volume?
Ex. in exercise, vasodilation occurs, and blood pressure increases. But, if the effect of resistance is greater than cardiac output, then blood pressure decreases?
Or should I ignore the effect of vasodilation/vasoconstriction on blood flow since it can vary?
