The Set Point and Feedback Control
Captions available
The idea
A set point is the target value a homeostatic system defends, per Bio 0051: receptors detect deviation from it and effectors act to reverse that deviation.
In practice
A rise in core body temperature during exercise is detected and corrected toward the body's set point through sweating.
Where people slip
A set point can shift, as in chronic hypertension, and the body then defends the new level.
