The regulation of mean arterial pressure involves the interaction between extrinsic and intrinsic mechanisms. While the intrinsic mechanisms can affect mean arterial pressure, they also play an important role in the distribution of cardiac output to individual organs. Discuss the role of the intrinsic mechanisms in the control of organ resistance.
