What is the homeostatic set point?

The homeostatic set point is the target value that a physiological variable tries to stay around. The body uses sensors to monitor the variable, a control center to compare the value to this set point, and effectors to adjust processes and bring the value back toward the target. This negative-feedback regulation keeps internal conditions within a narrow, functional range, like maintaining core temperature near its normal value or keeping blood glucose within a healthy window. It’s not the total ion content, nor the rate of ATP use, nor an external limit on enzyme activity.
