10^1000000 threads about this but haven't found the clarity I'm looking for...(already actually took the MCAT but thought this would be a good place to post)
Q=DeltaP/R
Flow is maintained by the pressure gradient (blood flows from high P to low P)
As the R increases, the pressure gradient increases (that is, there is a large drop in pressure when going from arteries > arterioles) - otherwise, flow would not be maintained. I understand this.
Vasoconstriction of the afferent arterioles...
