Now, how exactly do we multiply Q by a factor five? Well, one way to increase the right size of the equation is to increase the change in pressure by a factor of five. So we see that one way to actually meet this increase requirement of the skeletal muscle tissue is for the body to actually increase the change in blood pressure to 500% of its original value. 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.
