Now the problem with this is if we increase the pressure by that much that can basically pop our blood vessels, it can blow up those arteries and that can lead to many many problems. So we see by increasing the pressure by that much that can actually be dangerous. So what the body does instead, a much less dangerous and a much more effective way to actually regulate the volume flow rate to the skeletal muscle tissue is by controlling the resistance of our blood vessel, by changing the radius. So let's take a look at that same equation. So we multiply the cube by five. The question is, what can we do to the left side to get the factor of five?
