Homeostasis

By Renée Grinnell

The body’s tendency to maintain all its systems in a balanced state for optimal functioning, a concept first proposed by the physiologist Walter Cannon.

Example: If your body temperature is significantly over or under 98.6 degrees, your body is signaling that something is wrong or unbalanced. Once your temperature returns to normal, you know that whatever was upsetting the equilibrium of your body systems has been resolved.
