The importance of maintaining a stable blood glucose concentration in terms of availability of respiratory substrate and of the water potential of blood.
Negative feedback restores systems to their original level.
The possession of separate mechanisms involving negative feedback controls departures in different directions from the original state, giving a greater degree of control.
