System Level Physiology

Meaning

System Level Physiology is a holistic conceptual framework used in clinical practice to analyze and understand the integrated, interdependent function of multiple organ systems—such as the endocrine, metabolic, immune, and nervous systems—as a unified biological network. This approach recognizes that health and disease are not isolated phenomena but rather emergent properties arising from the complex interactions and communication among these systems. It is essential for identifying the upstream root causes of dysfunction that manifest as symptoms in a single, seemingly isolated system.
