Una de las contribuciones más importantes de Cannon a la medicina psicosomática fue su descubrimiento de la respuesta de lucha o huida (fight or flight response). Esta respuesta se activa cuando el cuerpo percibe una amenaza o un estrés, y se caracteriza por la liberación de hormonas como la adrenalina y la noradrenalina. Estas hormonas preparan al cuerpo para la acción, aumentando la frecuencia cardíaca, la presión arterial y la respiración, y redirigiendo la sangre hacia los músculos.

Cómo el cuerpo mantiene la cantidad justa de agua y electrolitos. Una de las contribuciones más importantes de Cannon
Cannon views the body as an "open system" that interacts with its environment. He illustrates how different systems (nervous, endocrine, circulatory) collaborate automatically to correct deviations. For example, if blood sugar drops, the liver releases glucose; if temperature rises, the body sweats. He refers to this automatic, unconscious regulation as "wisdom"—a design that ensures survival without conscious effort. | Law | Description | | :--- |
