Protein-Calorie Malnutrition Viewed as a Challenge for Homeostasis
In an open system, such as our bodies represent, composed of unstable structure and subjected continually to disturbance, constancy is in itself evidence that agencies are acting or are ready to act to maintain this constancy.
If a homeostatic condition continues, it does so because any tendency towards a change is automatically met by increased effectiveness of a factor or factors which lessen the change.
A homeostatic agent does not act in opposite directions at the same point.
Homeostatic agents, antagonistic in one region of the body, may be cooperative in another region.
The regulating system which determines a homeostatic state may comprise a number of cooperating factors brought into action at the same time or successively.
When a factor is known which can shift a homeostatic state in one direction, it is reasonable to look for automatic control of that factor or for a factor or factors having an opposing effect.”
