Answer: Option B.
The heart senses an increase in blood pressure and secrete ANF to decrease blood pressure.
Explanation:
Intinstic regulation is when a cell, tissue or organ system can adjust and respond to change in environment on it's own. The intrinsic is inherent in organ meaning the organ can maintain homeostatis within itself.
For example, the heart can perform intrinsic regulation for it self. The heart can perform myogenic regulation by reacting and responding to increase or decrease in blood pressure to keep the blood flow in normal blood vessel constant. It is a sublevel to control cardiac function.
