Answer:
Homeostasis
Step-by-step explanation:
Walter Cannon elaborated the concept of homeostasis from the investigations
carried out by Claude Bernard, creator of Experimental Medicine.
The concept of homeostasis, as Cannon formulated it in his capital work, the Wisdom of the Body implies a dynamic equilibrium, maintained interactively by the constant dialectic between internal kinetics and variations of the external environment. Homeostatic regulation is set to different levels, from molecular-subcellular to suprapersonal or social, through the global consideration of the individual as a whole . The study of isolated aspects of this systematic organization must give us, for strength, a partial vision. Human functioning is always influenced by a hierarchically organized activity of suprasystems and related subsystems.
